Since the free week of For Honor i restarted to play with some old player and new friend who missed this cool game and we all agree the one of the most annoing thing is the XP gain without the duble XP event.
Just to make an example grinding rep without orders take 8 hours of gameplay for 1 point rep and that is so painfull time investing wise.
For new player is really a pit since you got already a skill gap and no possbility on customise your stat, and for older player completely damps every tought on starting a new character because you already know how much time you have to sink on it just to have some cool stuff, (and dont get me wrong i dont think atm equip is op at least not like back in the day when full revenge set was so good) i talk about the armor skins like really 0-5 rep your armor looks awfull.
So i think my suggestion is pretty simple just increase the XP gain or decrease the XP needed to rep up because sink 64 hours to bring 1 character at rep 8 without order is just coconut, for the rest your game is great and a lot of fun.
Here are tips which are better than nothing:
1) Complete all orders without fail. They give bonus XP as well steel.
2) Use XP boost daily. Doing this three times a day isn't so costly.
3) You can purchase championship status which now gives a bonus 40% in XP per match.
4) Winning gives you a bit more XP. As soon as you find a good team in team modes, stick with them. If you have friends who can help out, even better.
