Funny thing is Brig. She used to get it fairly fast as she did good dmg to groups and healed a lot with inspire… but now she’s mostly a mid range healer that just uses Whip shot every few seconds her dmg is bad. Thus it takes way too long to charge an Ult lame as Rally.
As for Moria it can take a while if you don’t toss out dmg orbs. Which tends to be trash dmg that gives the enemy ult charge… Over all I think Moria charges fine, especially if your team is grouped up for AoE heals.
The main issue is just how easy it is to stop now. So many abilities block or cancel Coal now.
