Main Ideas - These idea's have been more fleshed out and would benefit both sides.
1 - Autoflips - I feel they hurt pvp way more then they help. With auto's few people are willing to take and or defend keeps when your hard work is gone 1m after you leave.
A: Get rid of them Entirely. <--gets my vote
B: If you don't want to get rid of them entirely you can put a timer on them so they can't flip 10 times in a hour or 2s after you take the keep. Perhaps once flipped cant flip again for an hour?
2 - Lockout - Too many times I've seen people switch to the winning side when it get tough.
A: Bring back lockout of 1-2 hours so we don't have constant switching to the winning side. <--gets my vote
B: Maybe give them some of type debuff that lasts 1-2 hours. Less inf gain. mastery or something?
3 - Scaled Freeps - Really need some love if you expect them to keep coming out.
A: Buff them. I'll leave the details to someone with more knowledge of exactly they need.
Misc Ideas - Less fleshed out.
1 - Creep quests - Some quests are never run, some dont count for maps when they should and some map quests take way longer then others.
A: Make DG quests count for Lugz. Make Grothum Quests count for Isen. Add a few quests to LC.
B: Possibly add a few daily/repeatable quests to give people something to do with less/no auto's (hopefully)
2 - Npcs - Not only do they add lag but they are ineffective at pretty much everything.
A: To reduce lag get rid of misc useless npcs.
B: Cut the number of npcs in keeps in half and triple the power of the rest. (No one should be soloing keeps in less then 10m)
C: Buff Ranger/Troll so they are actually worth rolling.
3 - Ops - Way to combat constant flipping.
A: Less Mastery Buff.
B: Inverse Buff - Keep the buff as is for the side that has it but give a Inf/Com Buff to the side that doesn't. I like this 1 personally since there's still reason to care about ops but less to constantly flip.
4 - Heals - We've got people on both sides way overhealing.
A: Straight nerf to all healing. Maybe 10-20%?
