Reality Check on the skins "you hate" - They keep the servers and RIOT running
Going to be brutally blunt and really concise.
League Servers are not free. In fact, they cost millions to run.
Many players do not spend much more than $10 on League, some do not spend any at all.
Skins are created both in demand (Annie and Teemo) and artistic choice (see Dragon Sorc Zyra).
Complain all you want, but someone (And A LOT) are buying these skins and they keep the servers going.
Lastly - ONLY RIOT has the full picture. Financial analysis, previous sales on a champion, purchase rate, cost of labour, lore/design choices and artistic choice.
It's fine to vent I guess, but please consider the above...
