This thread will no doubt descend into the usual, but rather than ignore the game mode entirely and hope for a simpler time of just complaining about Cyrodiil performance issues, I'm going to engage and give some constructive feedback on two aspects I think will improve the mode as well as make it more engaging.

1)

Context: I play stamina. It's my preferred style for several reasons. Templar in Vengeance is all Magicka.

That is problematic given how much nullification is rocking around just from NPCs. It involves a different playstyle, awareness and positioning. It make Vengeance not only a different mode but a different game from everything else, i.e. overland, dungeons, trials, IC, Arenas, IA, NM. It changes the relationship between damage and healing skills for those who play Stamina.

Players should have the same option they have everywhere else. To morph the skill into a different resource type if it can be in the rest of the game. The morphs don't need to be complicated and should add nothing to the server calculations. Just a simple "causes X magic damage and costs Y magicka" to "causes X physical damage and costs Y stamina".

It would add some build diversity and maintain a link with the rest of the game.

2)

This follows on from 1). I think allowing players to have some resource allocation would build on the above. Having a starting value of 25,000 Stamina and Magicka and allowing 10 points to be allocated as the player wants, with each point giving 1,000 each.

De-hybridizing somewhat, so that Stamina affects only Stamina skills, and Magicka only affects Magicka skills would reduce the need for the system to check "whichever is the higher of", which could marginally improve performance, and again add back some build options and theorycrafting to the mode.
