I used microtransactions a lot in LoL. My total spend atm is round R2500, but considering iv been playing the game for the last 4 years isn't so bad. I mainly used it for cosmetics and the occasional champ purchase. I HATE microtransactions in any game that offers the pay2win, mobile games are particularly bad with this.

I have bought some DLCs, but again I personally don't enjoy the idea. DLCs use to be patches that included major fixes and content updates, this was more a "thanks" from the creators for buying the game and supporting them. Now its just become another means to milk u further. Perfect example is the CoD series...
