Re-order your matchmatching columns.
Why have you got it so, so wrong?
Column one has
- Normal
- Dominion
- Aram
- Hexakill
Column two has the map and number of players Column three has the pick type / rankedness.
This utterly confusing, in how 5v5 summoners rift is normal, so is 3v3 twisted treeline, but 6v6 SR is not normal?
Lets make it clearer.
Column one: Which map you'll play one. SR, TT, CR, HA. Column two: what gametype you'll play. 5v5, 6v6, 3v3. Column three: Pick type. Blind, draft, ranked, ARAM.
There, cleaned up nicely.
