Should I bother with purple BW gem?

[Covet]

I'm close to my 1000 essence needed for a bw gem. I already have the Citrine. Is the +3 attack one worth it with level 50 coming out so soon? or will i be using it for a long time?

If you want Maximum attack power then yes it's worth also you don't need to get any new gem until (attack) Heptagon gem available.

 

Here a pic of (attack) Brilliant Heptagon gem (except diamond)

 

All gem with attack power stats is event gem only on other version and/or might be in cash shop rng box like this one on CN version (iirc TW had some rng gem box in cash shop too)

 

Since western doesn't like this kind of box so it will not implement to western version (at least for now) western might get those OP gem from event only.
