While I agree with the lack of troop balance… which unfortunately raid and invasion reveal most of. I found raid and invasion required me to think more and get more creative with my troops. In gw I can just use the metas or a few select troops… out of 400 or so I’ll look at the same 20 to 30 that I see in PvP and most of the time these teams will lose on sed anyway.
As for the option on which event… I think this will hurt gw more as it requires guilds to play and lose whereas raid and invasion can have either a few guilds play or a lot play without any major change in gameplay.
Imagine that some of the higher bracket guilds stop doing guild wars as they could get more rewards from raid… then guilds that cannot compete would fill in higher slots and since they would lose anyway merely register and claim rewards ending with a score of zero… this would go against gw as a competitive event and generally make it worse and undermine the event.
Guilds wars participation is mandatory for all guilds since even dead ones are put into play so that any new guild can get enough opponents to fight for the week…lots of big active guilds not playing would mess up the bracket system
