Would it be nice if we have competitive staples in casual rotation? Or should they stay in competitive?
Vigil/Coalplant/Ashville/Bagel/Villa/Warmtic/Clearcut are pretty fine for casual I feel (I personally hate Warmtic but I know it has fans). Product should most definitely replace vanilla Viaduct but I don't think we'd ever get that so it's whatever. 
And no, we probably do not need any more 'silly' maps but that's just my two cents.
