when you sell a champion it is reintroduced to the pool
so when you sell that 2star vayne because you haven't gotten a vayne for 10 rounds and you get a vayne the next round it's because you added her to the pool
3stars are over rated
few champions benefit from getting 3 starred
look at what the rng is giving you then try to build around it
don't go into a game thinking i want demon blademasters and wonder why you cuoldn't complete both synergies when all you had to have was 4 spatulas
item rng is getting kinda fixed in PBE
the AI is what makes some rounds amazing and others throws
it's what makes the game fun
every champion has 25% crit chance
unless you want to build assaassins crits are meaningless
if you build assassins you will feel the crits
yes every game almost every build will be attempted
the people that manage to complete them will tend to win
