What would be interesting would be to only give pips and rewards in unranked arena.
That way all people farming rewards from PvE, bots and casuals etc. will gravitate towards that mode.
The ranked mode can then be left for players only looking for the status of a high rank in PvP and a title.
if we do that we will get:
a lot off pro legend 5x teams that farm others on "new pipsed unranked"
more complex ranked gameplay - so if you have non meta build - you not have change to see gold or etc.
People trying to climb the season ladder for titles/rank placement will get less player count around.
We need what someone be in silver/cupper ..
