Last night I started thinking of build that would allow me to support my group in dungeons. Increase their health generation, damage and survivability while at the same time dealing damage and healing them in different ways sounds awsome to me. And I feel like it could be really effective to have a group with 1 tank, 1 healer, 1 dps and 1 support. The support can help the healer when needed, help AoE on adds and increase the overall effectiveness of the group with buffs.
This idea can be realized with most of the classes, but I went with Night Blade, simply because I like the ability to deal damage and heal the group at the same time and like how the class feels. This is the build: http://esohead.com/calculator/skills#cczz9MhesI8y1Rw8LxkS8heRJ8y1sj8Ir4d8IPq48IPSd8y1aY8A4fF8IPUI8IPww8L7JcdoQr6MdoQC6MdoQF6MdoQJ6MdoQK8v7HLanQ6ranS6Mhy3D6Mhx0n6Mhx0y6Mhx0l6Mhx0B8D7DrzdR6MIsaM6MIrv36MIrEf6MIrEh8F7JrzrJ6rzrO6Lbux6rbut6MIPNU6MIPAh6MIPAT6MIPAv8O7sLdeC6zAZqS6MA3FN6MA3FA6MA3FL6MA4Cb8P7sLdYf6zLp4d6cLncp6cLncn6zLncy6zLyjz837Vrw3Y6Lw316rw348zc7pcgePB6zgeXm6cgeXA6cgeYc
I think I will go mainly for magicka in my build, with the other 2 evenly divided, but I'm not really an expert yet on the attributes aspect.
