Not sure if this is a controller issue or an aim assist issue. Both are problematic at the moment.
Controller issues are likely to be around for some time still - Mike said they hope to have all of the issues resolved in time for 1.0.
Aim assist issues have become worse for some skills and playstyles with 0.9 vs older patches and the devs responded - see below
and then perhaps this is a problem specific to these skills…
