You are genuinely a moron. You think a disorganized rabble of hisec bears are going to ‘steamroll’ experienced and organized PvPers on a structure timer they are:
a) The ones setting up in the first place, dictating both location and timezone.
b) Will be prepared to defend.
c) Will invest in defensive doctrines for.
d) Will be able to cheese like hell (neutral logi, etc. All the same old things you always see from them)
Etc etc.
If you want to improve player retention, this really isn’t the way to do it. As someone with a lot of experience here, most of these people won’t undock for any fights, for any potential reward/war-end. The ones that do are going to be really lackluster in combat ability, experience, doctrine wrangling, organization and so on and so forth.
At absolute best, you’ll get a small fraction of each wardecced corporation showing up in some awful mishmash kitchensink that’ll get stomped and cheesed to bits by the actually decent PvPers who will know exactly how to counter these things.
As for mercenaries, again, actual mercenary here. Do you have any idea what it’d cost to hire a decent set of mercenaries to go up against a decent set of PvPers on a structure grid? It’s three ops, over at least a week. This will require payment for a sizable number of people, their deployment and staging, full SRP, etc etc. There was a saying a little while back, as far as mercenary work goes: “We don’t even undock for less than 5b.” That’s just to push the undock button in the first place, then you’re to cover all their potential losses, work spent on logistics and staging, all that jazz.
Assuming you’ll even find mercenaries willing to bother. In all likelihood, that market will very quickly end up dominated by alt-corp/alliances of the highsec wardeccers in the first place, scamming the bears out of their money, which then goes straight to the wardeccers who’ll take down the structure and reanchor another to go for the next few hundred dimlings.
