Have fun with no one there. Why would anyone do a public match now if there isn't an incentive to defeat another player's Lich if they get no reward?
And it's not about getting grief from people for not solving your order of req mods. If you let your Lich just sit there, when it can give progress to your entire group, then that's your fault and you should get griefed. And you say you're a weaker player too. So the rank of your Lich shouldn't matter, because again, if you're in a group with people they would be incentivized to help you kill it, and I would be since I'm always murdering everyone else's Lich for them anyways in public.
