Well I guess that illustrates it then… You are in fact able to play (and enjoy) CS:GO without having (or ever opening) lootboxes.
Maybe it wasn’t such a punitive decision by Valve after all.
To share my own similar experience, in MECHWARRIOR ONLINE, you use Mech Specific XP earned in each mech in order to spend Skill points on Mech Pilot Skills specific to each mech you own for Buffs. You can also convert Mech XP into GXP (General XP) that can be then used with other mechs but that costs money.
The idea is you can use your strongest Max Levelled mechs to help pool GXP for your new and undeveloped stuff, or buy XP outright.
My best (ie; Most Wins) Mech is sitting on 95,000 Mech XP that I refuse to convert into GXP… because… I don’t want to spend any money…hahaha.
But I still have fun… I don’t care. I just play like GXP does not exist.
Same thing in DIRTY BOMB, Weapon Skins are locked away behind boxes with Keys you can only get in random lootboxes or buy with money. Who cares? The default guns look like guns… they tend to look silly once you get the skins.
