special end of season rewards
due to the unwillingness of a large portion of players to even attempt many bases, i think it's only fair to reward those players that don't shy away from danger with an exclusive bonus at the end of the season.
the spirit of the game is to raid the most diabolical and brutal bases for glory (and genmat). however, this spirit is tainted by the current system of grinding low level, low difficulty bases to achieve the same end result.
so for those players that make it to the high rankings after completing a specific number of high difficulty bases (brutal and brutal champion) and stay there while continuing to do so - i think they deserve a special reward to properly show their willingness to overcome all obstacles for glory (and genmat).
going forward - i think it would be better for the rank system if there was a rank points multiplier for back to back completions (without abandoning). low level bases might have a facto of 1 or 0 (as 0•n=0) and higher difficulty might have a factor of 2 or more. you could multiply this factor by the completions value to get a bonus.
