The differences between seasons 1-5 and season 8
Because let's be real; seasons 6 and 7 don't relate to anything and were their own kind of messes:
Seasons 1-5:
Tanks: did some damage occasionally, took a TON of damage, lategame threats Bruisers: did and took a lot of damage Assassins: were a mess lol Fighters: did a TON of damage, took some damage occasionally, lategame threats Supports: Took lots of damage, dealt hardly any (save some special snowflakes), had nice teamfighting tools, sometimes lategame threats Mages: Team backbones with lots of dangerous tools, sometimes lategame threats ADCs: did a TON of damage, were squishy for most of the game, lategame threats
Season 8:
Tanks: what are those?
Bruisers: oh you mean tanks
Juggernauts: yeah that's what I said: tanks
Assassins: still a mess lol
Fighters: do LUDICROUS damage, get 1-shot occasionally
Supports: Deal TONS of damage, can take hardly any, can opt to buy teamfighting tools with their gold from kills, as if this is a team game anymore lol
Mages: oh you mean adcs
ADCs: do LUDICROUS damage, get 1-shot often early on, lategame overlords but what lategame?
