Reminder to Riot that the client and home website are an embarrasment.

Riot does SUCH a shitty job of explaining how their game works. They don't even have a glossary or any kind of page explaining the different technical aspects of the game; things like how Crits works, which abilities/ items proc Lifesteal vs Spell Vamp, how Armor and MR reduce damage, additive stacking vs. multiplicative stacking, etc. I had to do all that outside research on my own, through 3rd party websites such as the LoL Wiki.

This is, in my estimation, just another in a long list of things that makes this game hard to figure out and master. Riot pls.
