So, I am a big fan of new content and I love to speculate:
Share your ideas for what the new Hero Classes (Deathknight, Titan, and Oracle) might have in store for us!
Perks, Traits, Colors, Class Weapons???
Any Speculation is GOOD speculation! 
EDIT: @Ashasekayi found the details below and posted so, speculation is over, but as always, all spoilers are subject to change before release SOā¦ Enjoyā¦ for now.
Do you think Deathknight might bring necromancy to the hero class?
I am really intrigued by what Oracle might bring. Iām thinking along the lines of Enchanting and Mana Stormsā¦
This was the last info I saw posted by Lyya a long time ago:

PS: I put this in the spoiler category.
Also, happy forum b-day, @efh313! 
Thanks for the info @Ashasekayi and the spoiler. I didnāt worry about blurring the NAMES of the classes since a dev dropped those in an official post. But this stuff definitely should be.
Ironically, this was EXACTLY what I was looking for, but my search skills pale in comparison to you oh mighty kitty!
Thanks again, Ash!
Rawr. (And, youāre welcome.

Oracle looks extremely weak, Titan looks good in a good way, Deathknight looks bad in the worst way (may spurn one of the worst metas to date). Still holding out hope Deathknightās third trait gets reworked before they are releasedā¦
I āassumeā they already nerfed or plan to nerf Deathknightās last trait.
I really hope they go another route with the Titan class weapon before release. Thorodin is a shittier Warlordās battlecry (less damage even with the dependancy of 4 giants on the team and canāt be targetted), in addition giants really arenāt in need of just another meh basic singletaget spellā¦just saying.
They should rather make Thorodin something about heavy AoE damage or some added board control, or team buffing, strong status effectsā¦whatever, you know any of the stuff that giants really have a giant(!) lack off currently.
As much as I like the idea of USING itā¦ having it used against me is frightening enough that I MUST agree 100% with this. Its just not even reasonableā¦ 
As for Titanā¦ I may start building my team now!
Oracle needs to offer moreā¦ I like the class weapon but the third trait seems lack-luster when compared with Titanās for example.
I wouldnāt mind a 50% chance to death mark on 4 or 5 gem matches.
What if Thorodin read as follows:
Select an ally: Explode Magic+1 gems of that allyās color. If ally is a Giant, ally gains random status effect
That would provide explosion and status buffs which giants are missingā¦??
If Deathly Aura doesnāt get changed I expect people to do thisā¦
Why in the world did he took his hand over the mouthā¦made everything 10 times worseā¦
Because if he hadnāt vomit would have been spewing hilariously out of his sleeve!!! 
Ah yeah i left out explosions on the long list of stuff Giants miss, and i like your Thorodin more than the one in the files already!
Still would. The issue is that a single match 4 or 5 can cause you to lose a troop outright which requires a specific type of play and teambuilding that becomes grating over long periods of time. Doesnāt matter if its 50%, or 25%, or 10% all the way down until the point where people stop using it altogether. All this does is make it even less reliable on offense and even more irritating on defense.
Death Mark is just not a fun mechanicā¦
Or to be blunt:
Its hella fun on OFFENSE, when it procs,
but is rage inducing, vomit spewing madness on DEFENSE, when it procs.
Because of this juxtaposition of emotion, its a device that most players would simply rather not have in the game.
I would love for that trait to be removed completely but since that wonāt happen a 50% to death mark is better than always death marking. I would actually prefer death mark just be removed from the game completely.
AMEN. 
No way for us to know if most do or do not want death mark in game. But, I like death mark. That said, Iām sure that the forum will blow up with rage if anything in the game getās deathmark on 4+ matches. So, it would be better to just go ahead and nix it before the rage.
