I haven't spent a dime on this game and yet am going to finish on my main because i have been a very active player since syns came out, in a top 250 and more recently a top 150 syn. To excel in this game u have 2 options either pay or play a lot. Otherwise u have no reason to complain about an event being hard. Its not like u were not given a chance to build your stats to make this EB doable. And if u can't finish so what if u are playing at the level u should be based on your spending and activity most players on teams u face will be in the same boat as u and get about just as far as u so its not like u will fall behind in stats with the teams u face.
Why should a person that plays a couple times a day for a year or two be able to compete with a player that puts in at least an hour or more a day for the same amount of time? Only people that have any reason to complain are new accounts that were made before they removed the tiers from the EB and even they shouldn't have much right to complain because like in any role playing game it takes time to become strong and be able to complete events.
