Strikers have been complained about since launch. Only reason why the complaints haven't been as loud as they are now is because something far more annoying was always around the corner. Thorn, shot package shotguns, pre patch sunbreakers etc. You also have to keep in mind that because of the changes to both night stalker and sun singer strikers arne't pushed back really at all anymore. fire bolt would push any advancing titan back. even if said titan had primed the warlock with a well placed lightning nade. And stalkers straight shut down their mobility. But you can escape that now and freely skate away. In short strikers basically got an indirect buff because nothing directly challenges them anymore. the only thing that truly stops them now is a better player. That doesn't make them OP in anyway though.
