People say that "thank god riot stop release a champ every week because they were so unbalanced"
And now you see that the most played champs and the most fun and the most balanced champs are the old ones
and all the new ones are some overloard retarded kits that would have max/hp/true/shield/fly around the map/blink/gap closer/bruiser damage/tanks stats/assasin/support/with extra true damage....
lets see some examples by lane
Top OLD CHAMP
Top NEW CHAMP 
See where i am going here? "they release olaf in a week and he was ok and he is still ok they release camile after months of balancing issues we never seeher in games because always perma banned and riot would just make her useless by nerf her to the ground and thne nobody would play her..much balance.."
Mid Old champ
New Old champ
Jungle Old champ
Junglel old champ add what ever (Jungle is the only role that have neber been dominate from some new overloard kit always shift according to the jungle need and items rather than just being overloard kit someone may say about vi or hecarim but we see Warwick hit a 60% win ratio because feral we see reksai dominate we saw IVERN doing good is the only role that actually have some balance...(around champions)
Bot lane old support
Bot lane New support
(yeah braum wasent useless it was the case as camile broken and then riot nerf him to the ground make him a less better version of alistar... or put tahm here again overload kit with months of preparation...and then you have janna that was released in a WEEK broken or no still one of the best supports IN A WEEK not months....just show you
Bot lane ADC now here is a bit weird because all the old ADC are not in the meta (maybe some twich or sivir back in the day) and that an issue because riot after they start take long period of times to create a champion they add in every champion some sort of blink so in order the adc to keep in that they make all ADC to have blinks so ashe/sivir/etc got moved away for adc with blinks or high steroid damage...
The only champ that cause problems as balance issue was RYZE
Now lets see how many new champs cause balance issue and they still cause

All of them are balance issues (is not only who is op or no is who according to balance they do others they are useless other they are stupid to play against but nobody play them because they feel stupid but they are OP others are just str8 up OP and others are just a MESS of a kit)
And all this champs took MONTHS of preparation before release
GOOD JOB and lets see the new champion i am waiting him it would be like
"ok we have this champ that is support/jg/mid/top/adc/apc/assasin that deals true damage in every 2 hit equal to 15% of target current hp and max hp have 3 types of damage magic/physical/true have shields have blinks have stuns have tank stats have jumps have huge base ad damage so you dont need to build damage just some trinity and then tank have escape every 1.1 second and an ultimate that deals 100% of the target max hp if he hit them with the outer half of the ability but if you dont hit them you get heal for 100% of the hp you missing you even revive you self because f#ck it we promote bad plays so we forgive you stupidity dying in a team fight in 0.1 second because you know no possition! "this is where the skill of the player kicks in it would seperate the good from the bads in"-riot explaination for this ability
[slayer-pantheon-thumbs] good job balance team
made on purpose. its weird.
