towers are still toliet paper despite tower plating
i feel all it did was speed up snowballing yet delaying the end. if only if stuck under tower and cant last hit you should have Passive coin regen increase per missed minion under tower grants 4 or 3 gold while cannons are worth 1/4 their gold value if killed by tower. that would encourage a comeback worth stating. meanwhile tower plating just encourages hell to be raised later (160 per plate) plus its still toliet paper by the time you recall and get back to lane 3 or 4 plates or broken so yeah towers are weak.
i rather let a tower fall then to protect it if it cant handle a few champion/minion hits despite being full hp. personal opinion here towers do nothing while baron or infernal/ocean does hella lot more then a tower who cant tank a minion wave with 1 champion. i think towers need a resist and/or hp boost.
change my view if im wrong in any respects.
