As it was mentioned before, from both ends, it would be prudent to reiterate some stuff for Gondar (which I cannot see as anything or anyone else besides that of Bounty Hunter from Dota1/2)
Gondar is, in the ways that matter, representative of something akin to Pre-Hunger during his guerrilla days. Alternatively, he's also like a different flavor of Shadowcord, whose name we have yet to still actually learn. Shadowcord is a goddamn mouthful. He excels at basically being a Hunter. He is stealthy, he is treacherous, and though he's like bffs with Vanreir, I doubt he holds any equivalent value of 'honor' like Van did.
And, as already noted in a previous thread post, fighting Gondar is the equivalent of being harassed day in and day out. That's without even taking into account whatever bullshit Soul Evocation he has. Even if he was within Hunger's sphere of actionable influence, we'd have a terribly hard time balancing protection, chasing, and murdering the twit.
We have a ton of loss conditions. (Well, not really but a lot of those possibilities is gonna hurt the voterbase where it matters.) Gondar only has one. (Probably.)
And yeah, sure. We might have Wraith Form to survive an alpha strike. Gisena, Letrizia, and Shadowcord doesn't. And having to fight him outside? While being reasonably unaware? Just. Ouch. We can probably trip him up with social. Sure. But that means getting into some kind of accord that doesn't end up with any of our less defendable teammates at arrow point. Add on to the fact that he's literally "The Arrow." If he's got conceptual bullshit about "piercing through" (which is becoming painfully common) and "never straying from his path" (goddamnit), trying to change his mind is gonna be one whole truckload of "plot armor" to ablate it.
Age and Treachery...might not be enough in this case.
Alternatively, the fight will still be outnumbered against Gondar. There's a bunch of hoops that the guy still needs to pass over to actually be in a position to hurt us. We've got our own cloaking device too, albeit at a disadvantage since I highly doubt Shadowcord's ability can substantially overcome the rank difference. There are more vectors of danger (Letz in Verse, Gisena saying "no u" to esoteric stuff, Shadowcord trying to be Batman) that Gondar would have to face to get at us, and that would drive him to a state of mind that, if our WiS/Wits was high enough, we could take advantage of.
Also we have a fucking giant ass robot. Unless Gondar has an Anti-Skyscraper Noble Phantasm Soul Evocation skill tree, we can just have everyone get inside the Cockpit aside from Hunger and do what giant evil robots piloted by cutesy tsundere teenagers do best.
...basically, the disadvantages and advantages of the fight are highly dependent on how good we can bullshit our way into the upper hand. Par the course for most of our fights, really but I thought it'd be nice to lay my not-quite-definitive understanding of the pros and cons of fighting Gondar.
500 words if it helps.
Really need to keep doing more of these to not suddenly go into crippling arete debt.
