I have a 19 druid fc that is almost unkillable. Druids aren't much to look at in terms of doing damage but they are excellent support. When I wasn't running flags I was rooting people, putting faerie fire on rogues, sleeping hunter pets (they are annoying af) and tossing out heals. Any warsong is going to suck if you are faced against a few twinks when you have zero on your side. I like games where there are like 4-5 on each side tossed in with a bunch of scrappers. Games that are too evenly matched are fun from time to time but I get bored carrying the flag in two-hour long matches.
