To compensate for the immobility and the associated disadvantages:
Add a max 6 men healdebuff to magnet and rift for 9 sec. Maybe for only 5 sec.
Don't get excited right away, it would match with 6 pulled enemies by magnet and rift and makes the skills and pathes more useful.
Really a healdebuff at all is actually a must have, compared with other dps classes and consider, that st spec does not benefit from it and other specs have no burst damage, in addition u have to be tanky.
A healdebuff given by Blue Horror / Flame Turret would be another possibility.
Seriously both classes need some balancing.
Kind regards
