Guild Wars 2

I get tired of having to reset traits all the time. Between WvW and PvE, and all the various builds I like to play, I want a setup that works for them all. An All-Around Build…

So my question…would a 20/0/30/20/0 build work good?

Reasonings with the build:
-I only pay once to reset traits and don’t have to keep finding a trainer
-On-the-fly I can change my build out from Pwr/Crit to Condition to Venom Share, by just switching out gear and utility slots, and changing my major traits
-Allows me to easily hop between PvE, dungeons, and WvW, and with different build styles depending on my mood or what I want to play

Why I don’t take Counter Strikes line:
I know with power/crit builds it is almost required. However, I see it as there is only 2 good major traits (Hidden Killer and Executioner), and you waste 30 trait points in the CS line for them. The rest all seem pretty boring and repetitive (in some form or way adding to crit chance). And unless going full Glass Cannon, I think you can get enough Crit Chance and Dmg from gear. Just seems like I get more variety and useful trait options going down other lines.

Various builds for the 20/0/30/20/0 set-up:
Pwr/Crit d/d or d/p build

I would use the 1st build the most, in most situations as a survivable dmg build. I would obviously use the 2nd p/d build, mostly for trolling in WvW. Venom share mostly for dungeons and WvW zerg. And the spam build I find boring, so would mostly be for dungeons and high dmg/sec output if needed. All just depending on what I feel like playing atm.

So is this a good idea? I know usually Jack-of-All-Trades builds would be Masters of None, but in my mind for some reason, these build forms would seem to hold their potency.

Help and thoughts please!?
