This is a suggestion to change the skill progression system.
Bring back the old system but mix it up with some of the old and some of the new elements of the skill system.
bring back the specific skill exp per action,
keep the passive exp gain but make it more rewarding to active grind,
balance the required time to master professions,
I played 2 years ago and i was a miner/jeweler.
I remember it took me only a few weeks to reach lv 95-100 skills
if i grinded and it felt rewarding.
Nowadays i log in play for 15 mins and i have to wait a whole day and nothing to do with my skills to progress.
I dont say make the skill progression 5x faster but if someone plays many hours every day he shouldnt need 2 months to get from lv90 to lv100 in just one skill.
