I agree with the majority of comments here regarding his rework. It's nice on the core, but lacks the playability required in a fast paced game for now.
I love it (even posted this exact suggestion on the day they announced a rework for Vauban, let me have this, I'm old ^^). It's just lacking polish. Not enough reliability on high level because of their movement.
Didn't find any situation where I thought "This is what I need to change the tide of that battle".
Great ability, just too slow to deploy and lacking in damage without prior debuffs. On high levels you have to throw a debuffing bastille first (or go with weapon debuffs, aka kill them), wait for said debuffs, pack them by folding your bastille into a nice vortex, cast, wait and then voilà! Takes ten seconds. I don't mind photon strike doing explosive damage, but it needs an extra oomph to live up to its great visuals.
Nothing much to say except it's base range and number of suspended enemies should be slightly up (maybe 15 enemies and 2-3 more meters).
Vauban is a nightmare to build if you want a decent build. Because of his lack of survivability on higher level, you can't really enjoy the whole kit with an evenly spread modding. Range build for larger control and you loose on strength to capture enemies, meaning going back to Repelling Bastille and tactics we've seen before rework for ages. Strength build for damage/buff/debuff and you're toast on energy or duration (which means almost the same for a need to recast). Duration build can be done without much penalties but you'll need more slots and loose again on either, power modifying mods or survival mods.
Casting animations aren't the only penalties here. Throwing, travel time, wait for the grenade to hit, wait for the power to deploy. This would be easier if either, grenades deploy time was instant or if the powers were a little bit more efficient in return for waiting. And yes, he needs some love on survival. He could live up to Vauban's name with some armor.
Great rework but needs tweaks. Nervos clunky, Mine Layer forgettable, Photon Strike lacks something, Bastille could enjoy a 10% buff, frame too squishy.
Final comment, don't get me wrong, I love it. There's just room for improvement so that Vauban can be enjoyable on high level difficulty.
