... I would suggest that hosts who wish IC matches might want to not have challenger lists in the future to prevent such a scenario from occurring again...
No, that's not going to work unless challenge lists are outright done away with. Most of the jinchs require an IC portion (really a full RP fight, but the hybridization continues) consisting of knowledge and/or luring into a battle. That would mean that many of the current jinchs would not have challenge lists at all, and just short of going back to free-for-all biju matches, there would not even be a point of a challenge at all.
In contrast, if IC is first come first serve and everything is IC (as it should be btw) then we get to the issue of "nah brah, I been here like, a month just waiting to get into the gate, you show up and go through, bias bias!" and all that kind of nonsense.
... I told Yujo that, to my understanding, he would have to wait for me to finish my rp in Iwa because I have to hunt Eiko down IC before the fight begins.
If I can do that rp at the same time as the one in Iwa, or just start the fight with Eiko, I will. I did not think I could though...
To make you choose between which RP's you want the most is a tortorous way to go about it in my opinion, but you made your challenge while engaged in the other RP (from what I've read) with the understanding that you were the first challenger on the list (and a topic no doubt alerted you that there was someone patiently waiting).
My suggestion would be that if you really want to challenge still, negotiate that the IC finding quest be nulled (you would locate her and ID her as a host eventually anyways per the biju rules, so this just saves time) and you two just skip to the fight (IC or OOC). If IC, I doubt your fight will take as long as the Iwa RP due to fewer participants (then again, it's starting to wrap up from what I read) while if it is OOC it is irrevelent whether you are still in RP or not.
While I personally find that reasonable (the rules are fairly silent on what to do in the case of busy or missing challengers though skip is the implied for the latter) in the past I once skipped over a challenger (two actually) because they had other obligations.
http://forum.shinobilegends.com/index.php/topic,8031.0.htmlBatou and Ichirou (battle 3 I might add) which brought character Rikudo up in the line to fight. Long story short is that there was not much of a huge deal made about it because neither challenger protested (I talked to Ichirou about it, not so much Batou, I believe I asked around if I could skip him before doing so though) and I wanted to get the list moving.
I'm curious, what is the opinion of the current host on the matter? It is his/her responsibility to keep the list moving, whether she/he was aware of that or not, so I'm intrigued on what steps may have been taken to remedy this situation on his/her end. The general vibe I am getting is to skip Deathstroke with Raifudo's analogy as a summary of reasoning for it.
