Guild Wars 2

it takes 8.5 hours of game-play to complete a single track, it need to either be speed up or changed.

Sure, provided people make more in both of the other game modes for the same amount of time, but just to keep pace with inflation.

Otherwise, I’d rather the focus be more about increasing fun than loot.

If we just look at the reward track (and not counting PvE map rewards as some kind of reward track), the PvP and the WvW reward tracks are not that much different in terms of time needed to fill them up. It is easier to keep a max tick in WvW, than to constantly win in PvP (+ the time in a queue).

WvW tracks need more appropriate rewards though, as the “cost to maintain a character” is much higher in WvW (as PvP get all stats and items for free).

Hero weapons => still no achievement for them (unlike e.g. Auric Weapons)
Mistforged Hero weapons => unavailable (unless you have leftover tourney tickets)
Triumphant Armor => still no achievement (unlike Priory skins)
Mist-Statue decorations for GH => insanely overpriced in terms of Badges
WvW specific decorations (like siege weapons) => don’t exist, although you could re-use the skins
Guild Anthems => not working in WvW
supplies for scribing instead of Tomes of Knowledge => would encourage the use of tactics & improvements on camps and T1 towers too
No WvW season for years => but PvP is in its 5th + PvE Living World & current events
