Why is the game not as good as in s3-s5?

fair point, but at least to me lcs is also a lot worse than it was a couple of years ago, its slower paced, more boring to watch

That's because previously, teams would avoid fighting each other since there wasn't any point in doing so. All the Towers were equal early game, and thus teams could 5 man and trade Towers early giving their solo laner an "ungankable" lane to farm in. Games turned into base races without any fighting and global goon squad matches where the team with more global spells won. No one wants to watch a festival of players standing around taking Towers all day so Riot decided to remove the defense bonus from the Towers in Bottom lane.

The problems in LCS currently, are not related to the problems of the past Pro scene. Riot took away the shields and lasers from Towers which existed for a while (S5 / S6), introduced Runes which add more Healing & Damage (S7 / S8), added more champions and reworks with new mechanics, added more bans (in professional play this is huge as it limits a team's ability to counter strategies by other teams), and since the game's release have been constantly gutting and removing items which were fundamental to the game (Atmas Impaler, Deathfire Grasp, Sword of the Divine, Zeke's Herald, Zephyr, etc).

One mistake right now will literally lose professional teams the game. Even if the enemy team can't end the game, it will be borderline impossible to come back and acquire a W. Due to this, Pro's have to play boring farm lanes and hope they can out rotate or outplay enemies in team fights for objectives (aka - not fun to watch).

Whenever Riot tries to fix certain problems, they end up with even more of them. The only real solution is to do something drastic (such as change the map to have 4 lanes), in order to make way for a new meta.
