The counterargument is that shorter recharge=shorter duration=more time spent recasting it. The set shines in long fights, and Storm Cell is part of that.
collaborative missions only works if you have the same mission or missions that the game considers the same (for example, the Cimerora standard repeatable contact missions can be completed collaboratively even when the name of the boss is different). It won’t give you credit for a mission you don’t have.
It depends on the powersets. In a lot of cases, the Stalker is better dps, but not all. In many cases the Scrapper is much better at AoE, and they are a little tougher, generally.
In my actual testing (as opposed to my theorycrafting) of AR on Sentinels, I find the single target damage is still way too low compared to other Sentinels. AoE is fine. I struggle to take out many bosses, especially at the high levels. I would really like to see Sentinel Slug get the same lowered cast time as other ATs. I think that would help.
Another fix would be for contacts to offer you a list of available missions so you could pick the one you want.
Random Mission could be an option on that list.
My buddy and I sometimes fish (Abandon and missions, repeatedly if necessary) for missions in order to get the same one in situations like this.
I agree it's lame and should be fixed.
I love the AR changes. With the improvements to FA and FT I don't need any more AoE from Ignite, so getting a third blast is a nice improvement. Beanbag was always skipped, so Aim is a BIG BOOST. Excellent!
