Rn without boosters progress is genuinely terrible and im sure you know it. 1-2k xp per game without boosters just isn't cutting it. As an example to research a tier 10 it's like 400-500games if you get 1k xp consistently which is way to much just isn't fun playing with a peagun for at least 100games when you can't even pen higher tier heavys on their weakspots reliably and depending on the playtime you have it'll potentially take weeks to research a single tank. If i get a 6k battle in my tank the xp reward should be a lot higher than what it is. Grinding without boosters Feel's Genuinely slow and unrewarding. Especially after you decided to "make games last longer" so here's my Suggestion: make progress faster for good players with high damage in the battle by adding boosters to xp at different achievements within the battle like a 2x booster at 3k dmg or something like that
