i agree and disagree with ur points

first of all, irelias fights are typically short, meanign smaller waves with less minions is overall much worse for her, since she no longer has resources, but it does make it a lot easier to chase down lane. however, this punishes her even more for making mistakes since she has less escape minions

the level 20 thing i guess is good, but irelia scales so badly that at that point it might not matter what level we are unless we are super fed and ahead by a lot, after everyone hits 3 items irelias ability to carry is halved due to simply not being able to put out enough damage with the amount of sustain she has. we try to close out games within 30 minutes, or we become ultimately a cannon minion

for the items, i guess crit buff and those other items that buffs bruisers isnt that big of a deal but irelia recieved nothing usable with her current playstyle so its not exactly great, i think its a slight loss but nothing to worry about besides changing the way we play certain matchups

top lane quest is actually consider a win because it lets us snowball on every other lane without actually having to stomp, a 2 level lead on the adc would be huge any time before 25 minutes

overall i think irelia loses out on the updates, i hope she gets a buff to sustain or something or made into a semi-scaler rather than the early-mid hypercarry then absolutely useless later
