Guild Wars 2

Combo fields are already overpowered in large scale WvWvW battles. You can get 25 stack of might from fire fields to your entire zerg. You can have tons of area healing from water fields negating enemy arrow cart fire. You can give very long time (1+ minute) swiftness to your entire zerg from lightning fields. Need I go on?

Other then those 3, combofields are not (intentional) used at all in wvw, not only are the effects of other fields underwhelming, they also overwrite the 3 good ones, which leads to stupid situations, where ppl can’t use there skills, because they have the wrong fieldtype and would be counterproduktive (for example Necro’s Well of Blood as a groupheal overwriting waterfields).
Personally i think those 3 need to be nerfed, and others buffed. They are way too strong (especially fire and water) and result in extremely dull gameplay, with very little communication needed:
Cuddle → Use Field → Spam Blast Fininsher.

Does this also include weapon and skill choices? As in, will Necros still be able to start matches with Life Force and Eles be able to give their team swiftness with staff before switching weapons?

The life force should be fixed, but the swiftness through other weapons should definitely stay as I think it provides a neat little strategy with some risk involved aswell if you happen to not swap out in time

Where is the difference? Swapping skills to get lifeforce is also a neat little strategy, with risks involved, as you start with useless utilities, if you don’t swap back in time.
In both cases you swap to get an adventage early on.
Either have both or none at all.

We had sec classes in GW1. Nobody cared that we could use monk skills on our necros back than… why make such a fuss about getting burning
