Guild Wars 2

So far I know I want to mix being more support with healing and thrown bottles. with a bit of DPS depending on the situation so the trait lines I am looking at are tools alchemy and inventions, but not sure how much into each.

I don’t want to sound like a total kitten here, but the best course of action is just to try every possibility out.

No one can tell you better how to set up your traits then yourself.
I’ve changed my trait allocation ridiculous amounts (surely 100+ times) before I found a combination that really worked for me.
And I’m still messing around with the final 10 points to see if I can get better results.

Only advice I can give you is to trait for the traits, not for the stats.
And experiment! Dungeons and WvW are excellent testing grounds for new builds.
Oh, and support mixes great with condition damage, so you might want to look into that.

If you want to try out completely other stuff that requires other gear, try it out in PvP first or if you don’t like that, buy green/yellow gear of the TP.
It’s decent enough for testing out new stuff.

Taking inspiration from other people’s builds is fine, but in the end there will be no better build (for you!) then something you tailored for yourself.
