Obviously the person that replied to you plays on the carebear server. We both know why you want to go down the melee line! To whoop some ass as a warden!
At first in the druid line, I went down the Str line to make myself fully melee spec'd. And that worked for a while. But after talking to a few other wardens. I realise, that even though that 40% chance to double attack looks very attractive.. You're better of going down the sta line!
I realise this is the same as the carebear said, but I did it for a completely different reason. The 30 sec immunity to stuns spell. Trust me, that will really help you out in pvp!
But face it, your melee attacks won't nearly do as much dmg as your casting spells. Which is why I only tend to use my melee attacks when I have to chase after people. As long as you can keep them rooted, keep using your casting spells. They'll do a lot more dmg!
Aside from the melee line, I also went down the EoF line that gives me immunity to roots and most knockbacks (you'll want this for pvp). And it really pimps out those already overpowered warden roots! Yay
As for gear, try to get your pvp stuff sorted. My favorite tunic at the moment is the old Windriders Tunic from the QH pvp vendor because it has a de-agro clickie. But I also love the Jale Phlintoe or whatever the name is, tunic! For pvp the crown of enlightenment from SoS is very useful (the proc is delicious)! And the pants that fear from OOB! <3 my belt from Valdoons and Unrest... That is if you're @ T7...
Well, I hope my little rant has kind of helped you out!
