I don't think I've ever had a prolonged stalemate on glitters tbh. Not compared to other maps. I tend to be aggressive though.
I have a lot of hate in my heart. Going through the featured list for team games:
+ Intersection (rarely see good games, often leads to slow choke outs, ugly)
+ Akilon Wastes (rarely see good games, too big no metal, often bad games due to confused lobsters giving up enormous territory free)
+ Scorched Crossing (needs work to make it clearer)
+ Cystallised planes (poverty and slow choke out despite looking relatively open)
+ Wet Supreme (people don't know how to play it leading to bad games where entire sides are given for free)
+ Desolation (very limited fac diversity, often takes a long time to finish decided games)
+ Carrot mountains/fools mate (too homogenous) - though I don't think I've played they just look bad
+ skate park (I like the idea a lot, but the game usually feels like a standoff where I can't finish the game even if I win lane early - just have to sit on marginal advantage and hope a team mate figures it out).
+ Isle of grief (I loved the idea of this map on release, it didn't turn out to give games that I enjoyed)
+ Evorts new llamas (ugly, lacks intent behind design, arguably one of worst maps in pool IMO)
These are the ones I'd take out before the three already mentioned and I think for defensible reasons (not just personal preference). Yes I know this is subjective and some of these are fixable (especially scorched crossing which could be interesting if I could see the damn terrain).
There are a lot of maps in the pool that I don't personally enjoy much, but which I think should stay because it's very clear other people enjoy them and their removal I don't think is defensible.
