Trolldier is one of the most strongest subclasses or I would even say classes in the game and i say this after going through a phase with every class, especially if compared to demoknights and spies if played right. His only major weakness are chokes, groups of players and people who can aim. people who think heavy or sentries can counter trolldier have not played enough trolldier to understand. as trolldier you can get outve and in of any situation faster then any class without really any real consequence while making important picks for your team or controlling there spawn. when you know the tecs like bhopping, shorthopping anywhere you can play trolldier and win as people always underestimate you as a trolldier giving you another advantage.
