I'm an ele main and I'm very disappointed about Catalyst. The current version of the sphere is a joke. I'm not even gonna talk about the energy/cooldown of the skill, just how impossible to utilize them.
1. I don't play raid nor other hardcore PVE contents, but I know that a DPS class who can provides quickness needs to compete with quickness cFBs. And Catalyst can't reliably maintain quickness for the whole group and can't even provide quickness at the very beginning of the fight (no energy for sphere). And the group even needs to stand within the 240 radius circle to get buff? OMG seriously? Why would anyone choose Catalyst when others provide more to the table and not limiting your movements.
2. In PvP and WvW roaming, the sphere is a complete joke. Watch any streamers/youtubers playing catalyst in pvp or roaming in wvw, the sphere is just there to look pretty, doing nothing. No one would ever fight an Catalyst in the sphere. (Not that it's insanely powerful or something, just super easy to avoid)
3. In WvW zergs, given how mobile zergs are when fighting each other, the sphere is not gonna buff anyone, and it doesn't do damage either.
The whole class mechanic thing needs to be reworked.
