As Anet mentioned when the Path of Fire elite specs got introduced, some of them were designed to imitate the dual classing system from GW1 by mixing thematics of other classes into the elite spec.
I think this is a pretty interesting concept and I would like to know which thematical fusions you guys are most excited to see in a coming elite spec.
To show what exactly is meant here, 2 examples from the Path of Fire elite specs.
Spellbreaker -> warrior/mesmer
Instead of creating illusions themselves, a spellbreaker is able to see through illusions. On top of that is the entire anti-magic thematic of the elite spec. Countering magic has always been a strong thematic in the mesmer class, which they have now mixed in warrior with this elite spec.
In general, Anet stated that this spec represents "how would a warrior do mesmer-y things?".
Condition control would also be really fitting, taking conditions from allies and sending them to the enemy instead, which is a thematic of the necromancer.
Holosmith -> engineer/warrior
Holosmith gives engineer the "weapon master" feeling that the warrior is known for. Instead of carrying alot of weapons with themselves, a holosmith is creating weapons with the new technology of the photon forge, which allows them to use holographic swords, hammers, staves and dual wielded pistols.
Then there is also the heat mechanic, which has some resemblance thematically and mechanically with warriors adrenaline system.
Mirage -> mesmer/thief
Using the deception skills from the thief and also a changed version of thief's "stealth attacks". Instead of triggering them by stealth, it is triggered by the mirage cloak.
Now the question is, which combinations can you come up with? I want to share some of my ideas here as well.
Plaguedoctor -> engineer/necromancer
Engineer is focusing on poison gases, diseases, acids and other putrid methods. This elite spec could also use a skill type that currently is unique for necromancer, corruptions.
The engineer is using powerful and dangerous chemicals, which have great effects, but are also harming the user.
Stampede -> ranger/warrior
Hommage to the bunny thumper from the first game, rangers get access to hammers and are using earth shaking attacks to keep their enemies cced while their pets are killing them.
Getting access to physical skills, which let the ranger perform attacks based on animal thematics (think bull's rush, but with other animals).
Maybe they could also have a mechanic to enrage their pet to increase their damage.
Might add more if something crosses my mind.
