Still, Sun Quan and Cao Cao as starters allow you to do either a Healer Team or an Attacker Team, though Attacker sucks to make cause the only good ones are REM-only, Healers are generally plentiful and farmable AFAIK.
Plus, Sun Quan gives an unconditional x3,5 whereas the only other great Healer team leader is the descended Valkyrie with x3 and that's only on her Ult Evo.
Shame you didn't roll the twins though, they seem like they are as newbie-friendly as Isis is (and that is saying a lot)
