Question about which class to choose again

[Hi]

I hope it's okay for having used multiple threads now.
Would anyone recommend a class between assassin, mage, soldier (I heard that's the best one) and some class with spear (I guess noble)?

My first playthrough was with acolythe but since I might try beating more heroic bosses I don't want to choose a too bad class. Assassin and mage seem most fun to me but idk if I can clear the endgame content without playing like a god.
I would prefer a class with spear over soldier, since the sword playstyle just seems boring to me but if it is by far easier playing with it I might try that.
If you can recommend me something and have ressources or something similar for a build (best items, talents, stat distribution, "playstyle" for endgame bosses) I would be very grateful.

Interesting you suggest those classes. I've done all heroic bosses with both a Finesse Spear build using Noble/Soldier while focusing on skills like Crash Down (w/Valkyrie Spear) and a Wizard/Sentinel spellcaster build, so it can certainly be done. Grey Wanderer's Shield is a must for mages, so it's good to get that. For nobles, Braern's shop sells eyes, so you can get in Amulvaro's Tower relatively early if that's what you're into.

Soldier is generally considered the best because of one very broken talent that turns all shields to S rank shields (except SS ranks, of course). Your Vados Shield (1STR) is now just as effective as a Dragonknight Shield (62STR). It's a saving grace for Finesse builds, but thanks to a very recent update, Mistra Shield (A rank 50FIN) blocks full damage now, making it a viable alternative to multiclassing into Soldier.

An interesting way to play Noble is specing into talents that give bonuses at 25% hp and multiclassing into Acolyte for the Divine Force ability (can't go below 1hp for 8 seconds). Nothing wrong with experimenting secondary classes, as you can respec if you don't like it.
