The "strongest class" really depends on what you're after. Do you want a class that's good at farming? At long quests like the Deepest Neverglades? Or maybe for a specific boss fight? The answer to the question varies and only fails to offer variety where DoomKnight is involved. The safest bet would be to say that all classes labeled as "tier 3" in the Armor Tier Breakdown are equally balanced together, and collectively make up the "second best" that DragonFable has to offer.
But if you would like some specific examples of which class is good for what, I'll offer these as my personal opinions:
Ordinary Battles (Single Target): Ascended Chickencow, Riftwalker
Ordinary Battles (Multi Target): Ascended Chickencow, Evolved PumpkinLord, Kathool Adept
Boss Battles: Ancient Exosuit, Ascendant, Cryptic, Death Knight, DragonLord, enTropy, Icebound Revenant, Master SoulWeaver, Pyromancer
Farming: Ascended Chickencow, Riftwalker, Kathool Adept
Endurance (Mana intensive activities): Ancient Exosuit, DragonLord, Pyromancer
Versatility: Death Knight, Cryptic, enTropy, Evolved PumpkinLord, Icebound Revenant, Master SoulWeaver
Obviously it's not perfect. But all or most tier 3 classes fit into at least two of the categories I listed. For general use, I'd probably look in the Ordinary Battles and Farming categories. Endurance is for really, REALLY long quests and boss battles where Versatility has classes that are jacks of all trade and can do a little bit of everything. Either way, you can't really go wrong with any of the tier 3 classes. Just use the one that works the best for you.
