In the first of these articles I'm going to investigate the Tanker Class and the power sets available to that class.
As a Tanker your role is to be first into the fight, to draw the attention of all the bad guys to you so the rest of your group can hit them without worrying about being hurt. The Tanker has the highest hit points of the standard classes in City of Heroes ( I say standard because I have not played either of the prestige classes yet). You also do a medium amount of damage. However a high amount of Hit Points is only part of the battle, there are numerous different types of damage that can, and will, be thrown your way. Luckily the Tanker's primary power set has a number of choices available to you to allow you deal with this damage.
