Shield Experts

So...I'm coming off a little break from heroes almost two years (left to play Aion) and am now getting my feet wet again in pvp. My over priced old builds are still effective but very boring, so i decided to role a SD/DM tank and i have 0 knowledge of either set lol. Of course i fought them before but i don't really concern myself with other builds besides my own.

So I'm hoping someone who knows about that build can come on here and get me out of the dark. For starters what do i take out of the primary and what should my defensive goals be? Than what do i take out of the secondary?

What made me want a sd, is i saw some guy with one the other day and he was awesome to watch, and i remember before my break shields was trash, but it seems it's at least viable if not good properly built. A side note any builds thrown out there would be greatly appreciated thanks in advance :P

Also i plan on strictly zone, with the occasional lolfiteklub, don't ask why i get kicks out of it sometimes i just do lol.

I know shields are rare but wow lol, it has to be one person who can point me in the right direction? All the searches i come up with non list pvp effectiveness it's all pve stuff, and as we all know it is two different games

Shield defence is very viable for zone play(as long as its on a tanker). Mainly try to build up your range def to 70% if you can get it there. Then some hit points and recharge. One with the shield should cap your hp and make you very hard to take down. Sorry I can't help with Dark melee my SD tank is SD/SS. I would also recommend the destiny with the heal and regen component and aid self.

I just don't get how to do it i must admit lol, even slotted with a full pvp IO build i couldn't make it work i was forced to run run run, everyone hit me at will never missed lol.
