Abandon Penalty Even Though I Joined Back Due To Crash?

My game crashed mid fight I join back no longer than 30 seconds after. We go onto win the game (I drop the most damage) and I somehow don't even get any RP. I actually lose 90RP+ which would have boosted me into diamond. Yet I'm back to the middle of plat 1. That would have been over 300+ ELO if my game didn't crash. EA, please help this make sense. This abandon penalty isn't even fair and used properly?? I believe I posted this before but I can't seem to find the previous thread.
