I feel that buffed nasus hits his high too quickly
Disclaimer, just got shit on by one. Not a rage post, however. Just opinions.
We did not handle nasus well early, losing the first event. By the second, Susan was snowballing, and at 12 minutes he was approaching 800 stacks, a critical mass that's almost impossible to deal with. (screenshot included since i have seen several threads of people claiming even more nuts numbers) While NB is pretty snowball-y, I do feel that it takes other snowballers, even master Yi, longer to come online and when they do, if my team makes a solid pick it feels like we can still kill (partially thanks to the on fire buff) and possibly come back.
Nasus does not give that feel, and so I think he should take longer to come online like that, even if mishandled early.
