Warcraft 3 MODs

Hello, just wondering. If you start the XP multiplier at 1.5, then increase it to 2.5, will it affect everyone? Like let's say you just leveled up to level 8, hen I increased it and do a map change, will you go down to level 7 or level 6?

1.5 to 2.5.

Will they lose the abilities too and all fall back to what is required at xp 2.5?

yes, their level is based on xp, so if u set it higher, players who had level 8 probably will go down to 5 or 6

But how come they still retain their ultimates when their level went down?

Probably a bug

yes its a bug, when the retrieve xp and skills, they have the ultimate skill, then they lose some skills cuz the got less levels, but they dotn always lose their ultimate first when going under level 5
