S2 recently released a sneak peak that Pollwog Priest is getting remodeled for the next patch.  This is partially just to make the hero more appealing and fun to play, and partially to improve its stats to make it a more competitive hero.  Here is a look at the changes (new look above):

Pollywog Priest
- Remodeled and effects redone
- Range increased to 550 from 500
- Base Armor increased to 1.30 from 1.14
-
-
-

New Electric Jolt spell (same basic concept as old version but should work slightly better):

Instead of Magical Bindings, the Pollywog Priest now uses Tongue Tied (same effect on target but much funnier):

Morph now changes the target into a Toad:

Pollywog Priest’s Voodoo Wards ultimate now summons Tiki statues that shoot lasers!

SPOOKY!!!!!!
