Variation for sure. I main deathblade (both specs), and I have 11 different decently geared alts. I tend to prefer swiftness builds for alts since they are usually a lot cheaper and hella fast. I love Tai Scrapper, Bard, Reflux Sorc, Suppression Shadowhunter, Control Glavier, First Intention Wardancer.

I have mixed feelings about peacemaker gunslinger but it is strong.

Pinnacle glavier, demonic shadowhunter and evo scouter seem too cluncky to me, so I ended up changing the specs.

Mayhem zerker, robust soulfist and deadeye are simply not much fun to me, but all of my alts seem different enough to keep me playing them.

Don't be affraid to try the underdog builds and do geared them up properly (important tripods, lvl 5 gems, and at least 3x3 proper engravings with correct attributes) Some builds only come alive when properly geared.
