Currently, in DDO there is a huge incentive to play DDO in the epic levels in a destiny which ill fits a particular class. I think that it is silly to run around in Legendary Dreadnaught on a cc/healing bard, or Draconic Incarnation on a fighter or Fury of the Wild on a wizard. The devs should not incentive this practice like they currently do. The first change I would make to the epic destiny system is that a player earns epic destiny xp in whatever destiny that they are playing in and can then allocate those destiny points in any destiny that they have access to (e.g. a fighter runs quests and earns destiny xp in legendary dreadnaught and then can allocate those points to Draconic Incarnation if they have Draconic unlocked).
Some previous proposals have penalized players when they run in the prime destiny like for e.g. a players earns 50% of the xp in a capped destiny to be used in other destinies. I think that illogical. Why should there be any penalty? Why in the world would we provide an incentive a fighter to run in Draconic Incarnation which a penalty would do. Is it going to enrich the fighter's playing experience by running around in Draconic Incarnation? I think not. If the devs are worried about some sort of balancing issue i.e. the game is not balanced around players running in the primary destiny - swing the nerf bat on all destinies - just bat those down because a fighter running in Draconic Incarnation is dumb.
The next change I would make to Epic XP is level 20 quests should not give the same xp as level 27 quests per minute. Level 27 should give more xp. Give the level 27 quests more xp so people are incentivized to run new content. The devs do a fabulous job making new quests so why the heck are so many people running Level 22 quests that have been released for 1-3 years. Come on now devs give the players more incentives to run newer content.
This next change is a change that I would really like to see. Double or even tripple the xp awarded on epic elite. Why in the world does epic elite not give the same xp per minute as epic normal? Does this make any sense to anyone? At the very least epic normal and epic elite should give the same xp if not epic elite should give more. Give a first time bonus and saga bonus so players when they level want to run a variety, but when they have run out of quests which they will get them playing epic elite instead of epic normal or epic hard.
What I would like to see in game is running my fighter Norg in epic elite at level 27 quests (29 on ee) in legendary dreadnaught instead of running Norg in epic hard or epic normal in level 22 quests in draconic incarnation. I would like to see tons of lfms for the new content on epic elite and all difficulties instead of what we have now which is basically none. Make it so Devs.
