Balance in League of Legends

I know that riot will probably never look at this post but i will just hope. So, the main reason why im making this post is bcs i think that the game lacks balance and if riot would actually pay attention to this i would b happy bcs lately im having a lot of issues with the game and this makes me so frustrayed sometimes and the reason is the new mage reworks and the fact that there are champions out there like tryndamere for example that lack counterplay a lot (given that trynda is a champion that can 2shot squishies just by auto attacking while being immune to death for 5 seconds and have a heal that fills 1 third of his hp bar while also can ult while he is mid air, stunded and silenced at the same time) and this is just ridiculus given that he still has the crazy ammounts of dmg, a dash that can save him or help him reach u easier and a slow that lasts for quite a long time and can b activated when u try to escape from him.

Also i understand that putting balance in a game with so many champions is hard and practically even impossible but the release of even more champions doesnt help the game become even more balanced, besides i dont think that the players really need all those champions since there are quite a lot of them in the game already (in other words i think that releasing new champions less frequently would help the game be more balanced and lee obnoxious and annoying)

please take this post into consideration and excuse my english since im not a native speaker
