Ranger 3 specializations
Need a bit more information …
What are your first two specializations?
What game mode are you playing? Open world pve, Fractals, pvp, wvw?
Probably marksmanship, beastmastery and wilderness survival.
You’d probably go : 
- marksmanship for the longbow
- skirmishing if you like to often switch weapon
- wilderness survival for utility and resilience
- nature magic would also be a good choice if you are good at stacking boons on you
- beastmastery if you rely on your pet
                                    No core profession should be balanced around an optional elite specialization.                                
                                
                            Thanks for the info and advice
