So at best means pre-nerf while at worst means post-nerf?
Telly Before Nerf (without Vela): 11.2%
Telly After Nerf (without Vela): 10.9%
Without Vela, Telly is comparable to GM whether it is at best or worse form.
It is with Vela that Telly overcome GM by a landslide:
Telly Before Nerf (with Vela): 19.6%
Telly After Nerf (with Vela): 16.1%
So it is clear that Vela is what make Telly become so OP.
That is why I disagree with your post here:
I said Telly-Vela combo is OP but you cut it from your quote.
Can you look at the alliance leaderboard, what is the rank of your alliance?
