6.2 Dark Seal is a huge buff to singed players
I want to point out that now you can start refillable potion and don't have to proxy the first 2 waves if it's an abusive lane bully. Shove the wave hard, proxy the next and back, you can now pickup corrupting and build towards rylai's and walk back to top :) Also i've tried the double dark seal which really strong and the healing stacks.
