Everything aspect of the hero is rated on a 1-5* scale.
Weapon: (*) Another midline automatic weapon for the DUD pile. Armor calculations ensure his weapon is only going to tickle enemies at most.
Defense: (***) He’s basically got Ryker’s defensive stats. Not super squishy but he can’t take a beating either.
Bronze: (***) This had the ability to be a game-changer but its largely been a disappointment. As an AI, Wesson often won’t get this skill off until 40+ seconds into the game. Several times I’ve seen Wesson finally fire this off only to have it immediately Sterilized anyway. If you pilot Wesson (which you shouldn’t, he hits like a wet napkin) you can fire this off as early as 20 seconds with perfect aim, but the short (8s) duration will leave you underwhelmed, often your heroes are reloading, moving from cover to cover, or are stunned/staggered themselves - and all the enemy has to do is stay in cover or roll around and they will usually be fine. Meanwhile Nightingale has her Mark on a flat 15-second cooldown and hers gives each member of your team 15% more crit chance and thousands of DPS, even if they aren’t shooting the marked target - and her skill lasts 10 seconds. The reduced max HP is only useful if the target is already close to full health.
Silver: (**) Guaranteed damage on the entire enemy team, and the damage is better than most similar skills (Bladestorm/Clean Sweep/Corruption) but only if the enemy is out of cover. What makes this skill poor is its longish cooldown (30s) and conditional bonus damage. If the damage was more consistent or the cooldown lower this skill might have been good as I think teamwide damage + stagger is often underrated.
Gold: (*) This is Oracle’s “Target Down” all over again. A conditional bonus effect tied to a long cooldown skill that is unlikely to ever make a difference in your games. Sometimes RNG might throw you a bone and burn up 2 spots on a limited cover row like the Frontline of Atrium - forcing 2 enemies to bunch up and be vulnerable to other ground effects - but the RNG nature, average damage, and long cooldown on Rolling Thunder make it impossible to utilize as part of a broader team strategy.
Platinum: (*) The bonus is a weaker version of Ronin’s Plat. While Ronin’s Plat could at least let you build a bonus team out of weaker gold/silver - this bonus is strictly limited to UAF/UAFA. Depending on your heroes that may make the bonus more or less limiting, but probably more. The reality is that running a UAF team for the kind of health bonus that Heimlock or Phalanx gives is pointless and the terrible DPS of this hero isn’t going to be redeemed by a modest damage bonus under the condition you run an awkward energy-heavy lineup in a metagame filled with mech DPS.
Conclusion: (**) A weak hero. His only niche is as a Marking hero that makes it possible for bots to focus down a hero that is on a Mandrake + Multi-Healer team - but possible doesn’t mean probable, you’re better off with Nightingale throwing out marks every 15 seconds with a big DPS boost and getting lucky with a gap in enemy healing (most enemy heals aren’t ready by the first mark anyway) than you are waiting until the 40 second mark for Wesson to try his luck with a shorter Mark with a heal blocker but no damage bonus.
