@Iron_Guard8Nice ideas.
Gw1 Ops had the best maps and after playing them recently I realized just how much the enemy hero ai likes to screw with you like soldiers trying to position on rooftops and rocketjumping when you get too close or scientists teasefully waving at you after warping. The challenges were pretty hard but I wouldn't mind some returning like having,to disarm the zomboss airstrikes. Gw2 ai does this to an extent though too.
Pots were glass cannons they could deal massive damage (especially bamboo shoot) but they couldnt really take it from enemy classes and half regen is a pita to deal with. They had the biggest number count and best positions though.
Gw2 Ops improved the challenges and offered the most enemy variety with the classes being well spread out and more damaging variants used on higher difficulties and gave us solo play with reliable bot companion. Enemies like screen door and the coffin/outhouse zombie were stronger.
Bfn ops just sucks and the common ranged ai need to go. Reduce ranged attacks from the ai in general.
An improved backyard would be the best hub as giddy park quickly becomes boring without people and lacks the tonal balance of the 2 sides.
A refined pve that isn't collect a few items than kill boss would be nice but i could also understand if they just made an actual campaign.
Unlocking new ai to use is interesting as it gives incentive to play the modes.
Infinity time needs to be improved upon and the gnomes need more to do in general.
5 waves being a solo play option for quests so it doesnt interfere with multiplayer ops would be nice.
They should make crazy guarantee special waves.
Boss hunts should be separate as most of the elites in bfn were extremely easy or boring.
