gs-sword/focus attack rotation?
There isn’t a “rotation” per se, but rather you switch weapons as you need to depending on the situation. There’s lots of variables to consider, including spec and gear, that will affect how you play also.
If you’re fighting a stationary boss mob, your best DPS option is probably to get 3 Wardens up on him and go to town. However, the situations where that actually works are pretty rare. More often than not, the “boss” will have an attack that will kill your phantasms anyway, so you need to learn the telegraph animation and shatter before it happens.
I’m sorry I can’t give you a better answer than that, but there aren’t many fights in GW2 that are straight up “tank and spank”s like Patchwerk in WoW. You need to be adaptable.
You basically want to shatter in the middle of the animation of your 4th illusion attack, when you have 2 additional illusion attacks about to be off cooldown. Cooldown assessment includes weapon swaps.
So, yes you want to weapon swap pretty often. If you use 11111 more than twice in a row, you’re probably doing something wrong, unless melee range is prohibitive. In that case you’ll probably use a bunch of GS1111.
