I’m disappointed in this hero. He either needs a 3rd ability or his second ability changed.
Reducing 50% of DoT is still going to hurt. What is the point of reducing it when instead you could cleanse it or block the ailment like so many other heroes do? The only reason i can think of is for undispellable DoT heroes but that is not a large list. Jabberwock and Natalya?!
Zim hits all enemies (though lower damage), gives an attack boost, AND cleanses at fast speed. Reuben only does 215 to 3 heroes at fast. Cmon that is ridiculously low when you look at how lame his 2nd ability is. Drake at the same speed does 270 to 3 heroes. Captain Kestrel does 215-333 to 3 heroes depending on mana. White Rabbit does 280 to 3 heroes.
Reuben either needs a 3rd ability something like reflects DoT damage back to the enemy or give him a cleanse or ailment block.
Obviously, for people with a small bench, he will find use somewhere on your team. For people with a medium to large bench, he is severely outclassed in numerous aspects.
