I'm not a warden's expert, just a casual who tried several times it about some versions.
I agree that, on Phoenix server, warden is unpowerful cause no shield spec. However warden could be cool, you just need find your way regarding some keys points.
1. If you would 50 in weapon choose blunt (better for solo spec but could find a slot in smallman)
2. Parry is a solo's skill, added with Mastery of Parrying lvl5+, any pbt, shield, etc. you look like a wall (but fight will be long ... very long)
3. In smallman, cure disease is obligatory. Some ppl will say that rez lvl 16 too, not for me
4. If you choose regrowth way, you must have 33+. Indeed, before spec single heal have no asset regarding basic single heal
5. Weapon with debuff could be nice (ex blunt from TNN merchand with D/Q debuff)
6. In RvR never forget that you have a bow, you can rupt healer/magician with descent range
Just some specs like that :
- 50 blunt, 38 nurture, 20 parry/regrowth
- 35 weapons, 45 nurture, 33 regrowth
- 29 weapons, 49 nurture, 33 regrowth
- 21 weapons, 45 nurture, 43 regrowth, 5 parry
- 10 blades, 49 nurture, 43 regrowth
You can have some exotic specs with only blue pbt but need open-minded mates

Regarding your SC stuffs, to cap in all stats warden is expensive. That's not impossible, just expensive. If you need I can send you my sc's file.
Hoping that help you
