When the game dropped it was 254, 96 vs 59, 58 (according to Guaton). That's +233 for Tag.
Set + to Guaton and - to everyone else and it is 250, 150 vs 150, 150. That's +100 for Tag, which means they lost 133 of advantage by lagging out.
If you can figure out a way to make closer to original HPs, I'd be fine with that. But you got no reason to say it's unfair to you, mm. It's not a brand new game, it's continuing the game that dropped.
