Being mainly a PvP player, ho mains a titan, i have to say, no, in PvP the storm caller needs a buff, in hig levels he barely kills a yellow bar enemy whit Almos all his super, and his damage reduction is not enough some times, same for the titan, he also need almost all his super to kill one yellow bar enemy. In PvP they certanly are powerfull but fearing that they do the same they do to the titan, i still say no.
