Good work, thanks for the efforts and contribution.

As an experienced player, I believe that I can point out many details which need to be improved. I will try to make them simple, some points may also provide with reason.

Friend system:
1) allow deleting multiple friends by 1 time.
2) set a wall for preventing spam adding.
3) allow showing basic details from request: Name, Level, Main knight Armors & stats etc.
4) new rewards for friends battle, current rewards are too low.

Armors:
1) transparency the number of material, so that players can see how many material they own.
2) allow overlapping material to save slots, or make the maximum slots to 80 or 100. (boss rewards may easily make people reach their limits, and for collectors, currently slots are not enough.
3) allow cancelling crafting process, return the 100% material and 80% or 50% golds.
4) also make the experience strip transparency (both armors and knights), so that people can easily track the exactly number they need.

Buildings:
1) add details of information for each level of buildings, not only maximum capacity, also golds earning for each levels.
2) add new function of building, like producing fusion stones or even gems (in very slow process), allow people choose the option of producing what they currently want (like Training fields can produce 48,000 golds per day, or 2 fusions stones or 1 gem etc.)

Map:
1) new expansion pack of map, more areas needed, dark prince is done.
2) allow remove arena etc. npc buildings from the map, no need to keep that.
3) new expansion, more slots needed.
4) dynamic way of gold spending, such as release gold store, allow purchasing material and other stuff from store by spending golds, not only accessories.
5) new NPC needed, can be used to farm material efficiently (not boring snakeskin, no meaning), do doing extra quests.

Chests:
1) make the probability of gaining each type of armors transparently, let people make their choice.
2) provide change log for each changing to prevent complaining and disappointment.
3) improve the enhance chest, add more useful armor and improve the probability of gaining rarest material.
4) make each level of chests become unique, make sure that you can only gain specific item in specific chests, not in both chests.
5) make the chest can only open by using KEYS, people need to use gem to buy keys then open the chest, and in this way, people who can get black keys from epic boss can spend several gems to collect 11 keys and open 11 chest by one time.

Fusion:
1) set strictly principle of fusion, like 3 stars+ 3 stars= at least 3 stars, 1 star+ 1 star = cannot gain 3 stars etc. make these clear.
2) allow getting +version armor from fusion. Once owned normal version and unlock the +version, should be able to gain +version from fusion, or allow combining two high level normal version armors to gain +version.

Boss:
1) improve the design of boss armor, current boss armors become much more ugly than before, but nemesis always with good looking, need to design the boss armor has better looking than nemesis.
2) balance the stats and elements, need to consider release specific elements armor to replaced old poor armors, like spirit/water and fire/wind etc.

Arena:
1) current reward has been improved, good, but not good enough. 1st and 2nd to 5th need better rewards, especially the 1st, need REAL valuable Legendary armors to stimulate the competition.
Arena is the final way of people competing each other, thus must make sure that people can gain highest reward from here, otherwise meaningless.
2) get rid of those hackers, in top 50, more than 80% person with poor armors and low levels, they need to be banned. Arena system needs a good order.
3) reconsider the matching system, release a new system which fits all range of players.
4) adjust the energy limit from 5 to 8, that's exactly 2 hours, easy to calculate and equal to the maximum double down number.

Others:
1) potions are useless for now, need to improve. such as allow healing all knights etc.
2) more accessories needed. Such as better looking capes, hats, hair styles etc.
3) rebuild the knight module, especially female, make sure that female with elegant looking, not a big fat body and face....also make armors best fit with female module as well.
4) improve the operation of game, when fast pressing the game will become lagging and delay, when continuing playing for a while, the game become slow (me use ipad 3), thus generally need to be improved.
5) give great rewards when finishing all achievements and quests.
6) open stats for lv100+ players, increase the rewards, not only 1,000 golds......

Hope GREE can consider these factors what I pointed out, thanks a lot.
