[EOTM needs love]

@RedShark.9548 said:It takes away wvw player that play wvw, but dont need those rewards anymore

That logic doesn't follow. If a wvw player don't need the rewards anymore and plays only for the sake of playing wvw then they would have no reason to play EOTM because EOTM is very different from wvw. And if that player plays EOTM for the new rewards then it stands to reason the same player would play any other new content that comes out for the new rewards and be away from wvw because of it. Either way my idea wouldn't change the way this player in your example behaves.

[A plea from the community - it's not too late to renege on mounts in WvW]

Mounts are great way for squad based builds that don't have much access to movement speed or 1v1 capability to catch up to the commander. Before mounts it's not fun to be ganked by random people on your way to the main zerg with basically no chance to evade or winning and have to make the run again or wait until commander waypoints. Mounts are a great QOL improvement in wvw.

To clarify this means EotM will have only its own reward track and none of the wvw ones so it will not take away people who want wvw track rewards from wvw.

A solution could be to make a map currency unique to EotM similar to living world currencies that get rewarded in an EotM only reward track and enable full pips. This map currency can then be used to purchase skins and items specific to EotM from a special vendor from EotM. This will encourage players to play in EotM but not take away from wvw.
