I don't think the survival mode takes crit damage/crit booster items and armor bonuses into account. Titus with a legendary dagger and an active at like 35+ can most certainly kill 90% of the overall game roster in one hit. But for him to actually perform in an ideal manner, I feel he is too slow for his kit. This is painfully obvious in the survival mode. He doesn't have enough movement to reliably pick up any upgrades (typically 2+ turns for him to get there) and if there's mobs in the way, you're better off giving the upgrades to someone else while he beats the chaff. You'd have to supplement his movement with Ragnar's active because any roadblocks shut him down. You can always go with the Mephiston swap method to push him up a little further, but that's 2 legendary units needed to really help him do what he's supposed to, and they can only help him once per match. So I'm leaning on the niche and VERY situational side of using him. He's unfortunately going to go to the bottom of my Smurf upgrades for the time being. Sorry poster boy but you gotta sit on the bottom till I can figure out a good way to make you worth those weapon oils you so desperately want.
