The first thing leveling a rogue in Legion Remix makes you realize is just how much rogue sucks in open world content. Fortunately the remix gear also shows a very easy way to fix it.
At lvl 80 with epic remix gear you can get a ton of leech. And while your damage sucks at first on heroic world tier, you can actually survive with 15-20% leech. So, all the class devs would have to do to fix rogues for open world content (and possibly leveling) is to add an early talent to the rogue tree that gives a ton of leech. It’s that simple.
