VR Templar PVE allaround flexible build

This build is excellent for playing in a group, but also great when you are playing alone.
It's mainly a DPS/Heal Support, and if you are wearing at least 5 pieces of heavy armor (highly advised due to the fact that you will be in melee range as DPS), you can also Tank with the Shield raised. Even with the 1st skill bar, you continuously support your group by spamming Repentance at every dead npc - giving them 250+ health and stamina after each dead enemy, plus a passive 15% regen to hp and stamina. If you go solo, you can replace this skill contextually with other useful skills, such as "Absorb Magic", "Harness Magica", "Silver Shards" or "Purifying Light". You could also use "Empowering Sweep" as an alternate Ultimate ability for AOE and additional Armor, to deal with a group of mobs.
For the healing part - I'm not a healer and have no gear, but when there was no healer, this build succeeded most of the time when the team was not just standing still and spamming skills. I was in 5 Heavy / 2 Light and still managed to pull trough most of the time. However, if you want to heal in a group dungeon, go for at least 5 pieces of light armor, otherwise you will run out of mana in no-time.
Spam HoT skills most of the time, use "Quick Siphon" on every heavy mob and boss you see (with the other morph it takes 2 sec to cast and thats too much), "Extended Ritual" when you see fit, "Ward Ally" when someone is really low on health, and save "Practiced Incantation" for those "O Sh1t!!!" moments :) (before using the ultimate, I'd advise "Unstoppable" if possible, to make sure you won't be interrupted).
As before, the 4th skill can be switched to other useful skills, but this one gives you that little extra to keep a party member alive for enough time so your HoT skills can bring him/her back to game.

Paladin 2H DPS and 1H & Shied Tank

Use Heavy Armor, fully skilled. Vary attribute values based on what you're getting from gear to make sure Magicka and Health are both overcharged. When soloing, exchange 1 ability on your bar for a self heal.

Imperial DK DPS 2h Weapon

B Tired and LAzy

If you are running around doing quests and you can barely keep your eyes open this build is a mindless grinder for 3 or fewer enemies. No need for pots. Run in hitting 5 then 1, or 1 then 5--what do I care? Or forget to hit them and run in anyway, still works. When you are in range, spam randomly 2 3 and 4 and right click if you care to.. Hours of half-awake enjoyment without fear of death (too often) or a need for attention.

This is just the trashy build im currently using in pvp, because I have nothing better.
