Before the patch cp into bastion was a must. Now that the shield is limited to 40/50% is there a specific number cp that should be placed into bastion? Any helpful info or links would be appreciated. (Not switching to stamsorc)
Use it to get to the HP cap, as long as you don't weaken the other CP stars. Eleven points can be a useful investment for a quick couple percent, while also granting you a situationally useful passive.
Yep, the Field Physician passive can be useful once in a while, esp. when you're expected to be rezzing. That said, it may be better to get that with points in Quick Recovery - if you're hitting the health cap anyway, it's better to get something out of the CP even if it's not much.
Before the nerf, I had the Revival passive (i.e. 75 points), and found it useful esp. in difficult PUG fights, but there's absolutely no reason to put that many CP into the tree.
Speaking strictly from a PvE perspective.
No but I still suggest 11 points in that section to get the 10 CP point unlock for 15% damage reduction while rezzing. This is from memory so I may be off a bit. Not in game atm.
