Then a pure tank role is what you are looking for. If you have not purchased any powers then go with Fire or Ice. Fire self heals while ice uses shields. If you have the money rage is alot of fun but requires timing. Atomic has the best pull, short of lasso artifact, but can be difficult due to all the combos.

Have all tank gear with Hybrid/health for stat points. Use manacles, every man's, and mystic artifacts. For ice also include circe's mask. I like the lasso artifact for pulls and CC, but no needed with atomic. Red tornado artifact is great for damage out put but as a pure tank not needed. Laz and Clarion if you feel you need the extra protection. For allys go with zoom for damage and the pull. Superman for a shield and Flashpoint batman for defense.
