Like the title says.
Maybe it’s just me but it appears that using sprint skill in challenge dungs with the effect / affix that shrinks your char has no visible effect on run speed despite the description of the skill. It appears to me the run speed doesn’t even get slightly marginally faster, let alone noticeably.
Run speed boosts from other skills (ie wrath of the berserker) and sources still seem to work ok.
Sprint should definitely be a lot more noticeable than WoTB run speed boost that’s for certain.
Sprint needs to be looked at?
