Keystones are not only a gameplay problem
There is also a thematic problem that bugs me since their release, the main offender being Thunderlord's. As you can see, it's visualised by a lightning from the sky - how the hell did
do that? I never knew he had a lightning powers? The same goes with
,
,
,
,
,
,
and whoever else. Another example would be GotU and BoS (which is reworked now).
Personally for me it took away alot of the feeling from playing different champions and actually makes me feel they blend, especially those whose best keystone TLD is, those playstyles blend into "hit three abilities".
Edit: Why is everyone here complete generalist? Why would we need to apply this logic on everything? It's just my bit on the problematic if to keep Keystones or not, not HURR DURR LET'S DELETE EVERYTHING THAT'S NOT JUSTIFIED IN LORE... ő_Ö
