Have you tried to do H2 SF solo? it ain't easy even with the OP comps so if all H2s including SF are meant to be done with just you and your comp I don't think they know what they're doing as SF will be impossible to do as they intend with this nerf.
Check your client to see if it has an ST in the lower left corner. If it does that's why it takes so long. My client downloaded and patched in no time at all.
BW and balance should never be used in the same sentence.
They don't know how to do that they never have, it's either make it op or nuke it from orbit.
We don't know yet if they just "tweaked" it or if they Nuked it from orbit with the mother of all Nukes.
Knowing BW's track record the latter is more likely then the former.
How about no. BW doesn't balance they make **** op or nuke them from orbit. You've been here long enough to know that as well as I do. I would rather just keep comps as they are rather then risk BW pulling another slot machine fiasco.
That's actually easy. All they'd need to do is set up companion preferences were players could set the order in which they want their comps to use their skills similar to how they did it in DAI.
Not just healing it's likely the tank stance bug where your tank has no armor rating and no absorb that's getting it killed and in true BW fashion they're nerfing comps healing but not fixing the tank until 4.0.3.
