A item revamp/rebalance is in need
Many items are way overfilled with stats and unique abilities. Especially bruiser items are the reason that makes them tanky if its possible and also deal lots amount of damage. Same items can be bought by assassins and lethality items give too much effective damage. Another reason is that many core items have cooldown reduction and its ridiculous easy to reach 40%,heck even with no items you can have 25% only from runes.If they remove the cap you can easily reach urf cast times with only some items and also gain huge damage damage stats. Lately we also see on many crt champions 2 or 3 Infinities cause the damage is too high and turns them into 1 auto one kill. Mages have access to huge utility options and defensive stats integrated in them.They can be technically mage bruisers. Items have very high damage cap and the only thing that counters them armor is non existent.for every 10 damage items you will find only 1 minor armor. Items that provide many different stats should have their stats lowered and some of the affixes should be removed and create new items. In addition to that there are some items that are totally useless in their effects and stats.
So Riot has to look at their items to fix some problems.
