Oh, just remembered one more thing: Mercenaries task completion voice lines gone .
This change has been recognised as a bug by the support, according to that poster, so I thought it worth mentioning here.
PS StarGust, what do you think about the bugfix of Neeru’s Implosion? I think it has fired three time at a single target (at least as of 25.0, haven’t tested it with hotfixes), as opposed to firing three times at random targets, as some people would expect. The wording there is a bit ambiguous — it’s unclear whether it should choose a random target and fire three times at it or shoot three times, each time at a random target.
