I do not like a lot of these.
1) No. count all 30 members, if you don't have 30 members in GW, make GW part of requirements.
2) that would be crazy. You would need 24 different troops for GW Defense. Maybe limit a troop to 3 appearances a week.
3) I find that Sentinels are actually not too expensive except attack. 600 glory and 85 gems is indeed a Lot, but mostly the 600 glory, as you CanNot buy glory in any way.
4) I Like the RNG bad luck that stops you from getting to the top fight and lots of points. I curse it when I Lose to several 5+ cascades from the sky, but that is what summoners are for.
5) Now THAT.... is an Interesting Idea. A Boss Troop, with Boss Stats and Power, might make things Way More Interesting.
6) I have heard a LOT about the problems from Weekly events. Please, PLEASE make it so that Any troop used in GW does NOT get the weekly bonuses, whatever they may be. So many times I have run into Double Bonus critters, or a whole team of Single/Double boosted critters has driven me crazy. Especially when they are a powerful troop to begin with. Find a way to do this? Please?!??
7) I disagree. I like that Monday is the Rest/Setup day. That should stay.
Good luck on Improving GW Devs! I hope ALL our comments help.
