Mister sinister awakening?

sfu_korax

Finally, after cyclops, magneto and double storms, i got a 5star mister sinister. I am able to take him to rank 4, and maybe rank 5 too at the future. The question is, do i use my mutant awakening gem on him? If I do awaken him, i can take him to at least sig level 100. I plan on using him offensively.
Drawback: my phone can't really handle his special 2 and special 3 animations, meaning there is a bit of lag while playing the champion. That doesn't really cause major problems though.
