swain does not feel rewarding/good to play

As a mage who has historically thrived amongst a wave of minions when fighting enemies it is pretty baffling that his primary dps skill is effectively useless when fighting enemy champions who are standing behind the wave. The range or passthrough or dps needs to be augmented to address this skill's failing. W is fine but has limited efficacy against the majority of champs due to their mobility. Even catching with e does not guarantee a w land, and since w is so central to the damage on r, its cooldown seems very excessive in conjunction with the aforementioned unreliability. The low ehp and long cast time prevents r from being useful as a defensive measure which makes it confusing as to why the dot is so poor, the range is so low, and the burst damage is mediocre and heavily delayed. Overall I would say good mechanics, bad implementation. With the lack of proposed changes to shift the meta away from its high damage state (which is what i was hoping would happen with a new season but unfortunately it looks like riot is going to let the dps meta fest unforeseeably long probably until the the game runs itself into the ground which at this rate wont be long). I would really like to see some changes to swain since the rework really did not improve his playability.
