Regarding the new Zenkai Goku his primary appeal comes from the fact that He has a special move that increases Special damage by 100%. Unless you can awaken him to Z6 he lacks damage modifiers and he can feel Lacklustre in various situations.
Welcome Shallot SS3, with the new update the new Shallot receives a host of stat increases, cover cut and damage modifiers. More importantly
HE CAN LEARN ZENKAI GOKUS SPECIAL
You wont have the Ridiculous stats that a Z6 Goku would have but you can have everything Else!
You have a unit that can Cover Cut 40%, Heal on main, Powerful Last-man standing Fighter with an incredible stack of Self Buffs. On top of that you have that Game-breaking Special Move.
Everything you could ever want in a unit, The F2P Zenkai unit. Why would anyone ever want to get a Z6 Goku when you get this Hero for free.
If I am way off please let me know. I have tested it in PVP
Very interested to hear your thoughts on the topic. Just seems too good to be true and by comparison makes Z6 Zenkai Goku seem so Bad.
