Thanks for the feedback man!
Appreciate your honest reply about the performance and portability, I definitely agree about the weight. The MSI GS65 has an 82Whr battery and it's light, 4.14lbs to be exact. It's just the upgradability that's a pain in the butt.
I'll put the ones you mention on my list as well, these are very similar to what I'm really looking for. Also, game wise; Destiny 2, ARK, Warframe and the one that'll eat up my GPU... Cyberpunk 2077.
