After seeing it beeing abused you can easily lock up to 2 ppl in place and they can t free themselfes at all…
the only 2 skills that could remove spider web are lp and crazy weed which requires a sorc/gene on your side.
you can also reapply the debuff while the debuff is active which is busted for all melee chars that can t hide or have range.
therefore i suggest adding a 10-20sec cd on the skill to restore balance
