Here is why I think this is happening...
1. We know older model devices have been disapproved as the reason for complications. 2. Reinstalling doesn't work and some have got a mesage claiming they need to update their app, making it our fault some how. (typical GREEd behavior) 3. There are the top guild(s) who are having no problem what so ever and are scoring 600k+ and above in points.
Soo... why is this happening but not for everyone, to me is pretty clear. GREEd has purposely bugged the game for certain players/guilds to work just fine regardless of which device model you use. Which in return allows 'them' (top guiros to reign the event). This no different than when a cell phone company (AT&T) sends out a software update which has a bug written in it to slow down older devices, so that you get angry and go out and buy the newest phone/product. In this case GREEd isn't wanting to by a new device they are allowing those who line their pockets to have the upper hand. This is no different than KA and MW where the top guilds spend ridiculous real cash which makes GREEd Corp. their money and if these top guilds think you shouldn't be able to roll with them they complain to GREEd and GREEd jumps on it within hours, where if I spot a hacker and report it 1 of 2 things happen. I get canned for slandering another player as being a hacker or nothing happens. Bottom line here is, the top guilds unitedforum, pirates this or whatever or whoever they are in this game, always want to be on top and lay large to be there and have a real connection and relationship with GREEd so everything is in their favor.
Oh! Let's not forget that many of you have purchased gems but can't use them!? Seems GREEd got theirs. The only solution I see is what someone else already suggested (sorry can't remember the name for proper credit) is re start the war after the crashing issues have been resolved and reinburst all who bought gems, then we all go at it with a fair playing field.
On a side note I'm curious as to what will happen with my accounts and forum account after posting this.
