Instead of leveling traditionally, players in warmode should have the option to funnel their future experience points into account bound upgradable XP tokens. IMO this should be a free quality of life perk to warmode.
This would be a benefit to those who are still learning to play their class and want to add more abilities at their own pace. Some players may want to experience their own sense of fun or set of challenges so that they cannot one shot every NPC for example. There should even be a warning to those who are about to out level their zone and quest lines etc, and be encouraged/informed that they can funnel future XP into tokens.
This would benefit those playing on Max level characters, they can continue to funnel XP into tokens for content that would previously award XP either in instanced PvP, or the Open World as long as they have Warmode on.
This can also potentially open doors for low level BGs to come back in a big way for those who enjoy PvP but do not want the variables Max level PvP adds.
I suggest three different slots to deactivate/activate equipped XP tokens, so you can funnel or stop funnelling XP into them. This would be per character, but they can be transferred for consumption to other characters on your account.
I think this would be a big win for casual and new players but I do have concerns of it being exploited somehow. There are technical stuff and whatnot I am not equipped to sort out. If discovered, I do think there are viable solutions. For example, cannot be consumed by characters over level 59.
This also competes with level boosts in the cash shop but this is actually a good thing. I think enhanced character/account bound XP tokens can be sold in shop too perhaps even ones that don’t require warmode in order for you to funnel XP into. So you can buy XP tokens that give bonus XP for M+/dungeons, quests/delves, Raids/Instanced PvP. I would prefer these cash shop options over the cash shop level boost and can even be perks for future expansion sales releases or new players.
