What I hope to see in 7.8+
A penalty for Queue dodging and Leaving. I love the setup Valve has; 30 minute penalty, 2 hours, 1 week, perma ban. League can be ranked or certain mode bans.
Keystones 1. should be more generalized; they don't allow players to diversify at all. Keystones 2. Thunderlords decree is MANDATORY on certain champions. AHRI high winrate. . ZED perma ban JUNGLE Skirmishers and Stalkers should be removed; Trackers blade should be default, with smite always castable on champions to slow them (mini exhaust) (Simpler interface in shop, and in general smoother gameplay experience)
SUPPORT Kage pick > all We wonder why caster supports are all the hype right now (Also blame the assassin update putting AD players mid) Talisman should build into Redemption Relic shield should build into Knights Vow
TOP/MID starter items Doran items should also increase your resistance under tower. (You buy these when counter picked or behind) Serated dirk's movespeed needs a cooldown. (AP mid's can't keep up. . except for Ahri and her quadruple flash)
Global attackspeed increase (15%) to smooth out gameplay. (Everyone running attackspeed runes is a problem)
