I've completed the game as a sniper assassin and I'm playing through again on True Vault Hunter Mode. For the most part my damage is scaling up and as long as I'm in the zone getting quick critical hits I'm handling normal mobs just fine.
Bosses and mini-bosses are giving me the most trouble. Often I have to get close to spawn them and my first reaction is to hit Decepti0n and sprint away. But most of them can close almost any distance in one leap and chase me as fast as I can sprint. With about 10k/10k shields/health I can only take a few hits and have to rely on health stealing grenades and repeated sprints to try to kite the bosses. Mini-bosses are often in confined spaces that get me killed quickly.
Any tips for slowing them down so I can get some distance?
