For me if riot want to nerf Teleport they should nerf ignite too!!
I mean lets face it ignite is a summoner spell that require 0 skill to when and how to use it...
All other summoner spells need to think before you use them!!
Now if riot want to nerf TP and make top lane more brutal with fights 1vs1 and stuff then they should really nerf the early damage of ignite and buff it by a bit later on
the first 3 lvl of ignite damage need to go down in order to top lane to not become who ever put the ignite the 0.1 second earlier took the FB and won the top lane
