Healing vs. Anti-Heal

Started noticing this last night. Anti-heal feels pretty useless right now, whilst healing feels a lot stronger. Champs like WW and Trundle have been unbeatable even with max. anti-heal measures, they can easily sustain 1v3 situations, be fully focussed and heal through the damage - unless perma cc'd. That said self-healing on other champs also feels oddly strong. Anyone else?
