DoH and DoL experience events.

I would personally like to see some experience events.

I would suggest having experience events twice to three times a year evenly split across the months. It would encourage players and their interest in the game.

It's an 'extremely slow' process and in the long run, subscription schemes such as this grind system will only make it worse for subscribers the playerbase's health. Make them wanna come back for this. It will work with the setup of how the game runs.

If you could participate in PvP at level 10 and be bolstered to 60 or cap to earn experience, would be another way. PvP is also poorly attributed for the game's features.

A burnout inducer and subscription killer.
Experience can even just be increased by an extra 50%. Generous for 100%
A lot of friends and players I've communicated with agree with this notion.

(and reiteration)
TL;DR - We desperately need experience events to kill the boredom burnout, be it twice or three times a year.
