What was the best season of league in your opinon

I joined league in the middle of season 1 on and off and I started playing ranked in the middle of season 2 and was at like 500 elo :( season 3 I made it to silver and hopefully by the end of this season I can make it to gold personally I really liked season 3 I missed the lost items of season 2 but I liked all the new items they put in even more and after "league of black-cleaver" and "league of warmogs" it was a great season I don't have much room to judge season 1 since I thought everyone was OP with my level 10 Ashe mid season 2 I liked it I got understanding of the game but there wasn't much customizing in builds season 3 like I said 4 weeks into the season is when it really got exciting no matter what role you played you were building something different from the enemy with the same position In season 4 I just don't like it at all it seems like the same champs have been viable all season there is no vision control anymore because people forget they have a trinket and we're back in the same boat as season 3 with wards except people still know they have a trinket and think they don't have to buy wards. but this isn't a season 4 rant just wondering what your favorite league season has been
