Hello, sorry if ya were ignored for a day.
Your still pretty low level and hopefully you will get some good Epics, a free Pan Goli is guaranteed just by doing the 28 day sign in and he's a real nice one to have.
From what I see there is a sharpshooters build in the making.
Pyro Petes skill carries over to all ss in battle, so the mercenaries of Renee Ven, and Blitz Bomber will be using PP's skill. You are missing a part of a good SS build thats Chiron. He's not to hard to get and one of the best heroes in the game.
Now thats not your top 5 but something you should consider when choosing a top 5.
You need 2 melee players and 3 ranged in most cases.
Dark Rider and Exokid are probably your best bet but Hercules is an option for your melee or tank type.
Sap does a lot of damage and very effective for new players in the Arena and GC and raids and LL. As time passes his rage cost is too high to make him effective as he used to but his high HP and damage done are always a plus.
Renee Ven with PP or BB until you get a Chiron
When you get your PG I would work on him as well, his skill kicks some butt, and you can phase Sap out of your top 5
