User blog comment:Commander Marko/Singed, The Mad Chemist (Rework Revisited!)/@comment-1330314-20130705055442

Your rework is excellent for the most part, especially the synergy between his Q and his W. However, the idea of selecting between multiple potions really steps on 's toes. It also gives him access to too much good stuff, despite the tradeoffs (bonus stun & heal, mainly). The active component on the ultimate is also not that useful, and breaks Singed's main vulnerability of needing to get close to poison his targets. The passive would also make him too strong during the laning phase (he could heal from trades a lot better) and force him towards a permanent + Potions start. I have a couple of ideas on how to change this, which I'll present in a blog post of my own.
