For all profs with roots. Current roots probably last too long for PVP, this a suggestion to change that.
Try not to focus on the numbers, more on the concept.
These roots would be short duration, but non removeable and in there own nanoline, so root resist/rage/free movement stims etc will only help against old long lasting roots. Unbreakable.
The new roots wouldn't be able to be cast on a target back to back either.
Take a look at Improved Complete Healing.
The recharge from the nano is short, but when used it casts a buff in the NCU that stops you casting it again for 20s.
The PVP roots could work almost the same, so you cast the root, which only lasts 10s (ignore the example numbers) but the target lockout could be 20-25s, and you can't cast it on him again for this time.
Only difference between the lockout on this and ICH, is the doc gets the lockout buff, but heals don't fumble or get countered. The lockout nano on PVP roots would need be in the targets NCU, allowing the caster to attempt to recast should it be countered by NR or if it fumbles.
The lockout nano would need stop old roots being used also while to lockout buff is running. This forces players to pick a old long root that can be removed, is breakable, faces root resist, but can be cast back to back, or a single land root that won't break or be removed, but has a short duration and a downtime between uses.
