Well, to be honest, Ironbreaker Bardin bot has one of the more sensible uses for their career skill. At least he utilizes the skill’s infinite block and aggro draw. It is troublesome, though, when for example (to draw from my own experiences) he just stands around blocking… on top of a downed player he could well be reviving.
To compare, the Dashers will chase every special (which is useful maybe half the time; the other half they’re just on the way) and the AoE skills will get used at the start of hordes. Including Unchained. The only ones approaching useful skill uses are the Trueflight skills, which could well have changed with the abilities’ beta behavior. So IB is just in line with the bots in general.
None of the bots seem to consider the effects of their Talents on their Career Skills, just using the default behavior all the time. This is just part of playing with bots, you have to take their behavior into consideration even when equipping them.
Also, this isn’t specific to the beta branch, so would probably fit better in the general feedback section.
