Then take a HW and Ganbatein lol.
You'll have to have YGs with you for that. Now granted, that's something you can have with you (a quick IW would void your efforts though, and Ganbatein fails quite a bit too, which can be annoying), but I usually don't plan on having to trash someone else's IW when I set off for an MVP.
The easiest way to ruin IWs is just to IW yourself and make a mess on purpose, overlapping ice walls at different times. Ice walls do not renew if you cast over them, so if you manage to cast a diagonal ice wall over a straight one, it will break. Or just use Sight/Sight Trasher. No YG and sure works nicely, too.
one, you used me and my ice wall to take SK
two, you attempted to break my ice wall so i would die
IMO this pretty much sums it up. There is no honourable behaviour involved from either party, simple as that.
For one, you took advantage of his IW; you already stole when he did the work, and then you complain about not getting the loots - how honourable. It looks like the one thing that you did is pressing the "Acid Demonstration" button four times from complete safety when he did all the work already. Deservant of the loots would be (depending on the map's layout, where SK was), if you were on the other side of the IW, SK would walk after you while you bomb him .. oh wait, you'd have gotten the loots then anyway.
And for the second point, it just seems you played dirty - so yeah, he played dirty too. End of story, everyone played dirty. No reason to complain about how unjust that was.
If one party really needs to emphasize the whole thing being FFA (with dirty play, stealing, trying to MPK and whatsoever), crying "unjust" then seems quite hypocritical.
But that's just me. IMO, if you're playing dirty, you really need to know what you're doing, and deal with the consequences and not complain if others are playing dirty too then.
Made a rant because of a FoH and steals loot himself?
Actually I think it was someone else ranting.
Edit: there you go:

I even replied to it - good to know I'm being somewhat consistent in my views, at least.
When i see some bio ran around i tell him, let me have mvp and you can have the loot, when i am hunting for exp and not for loot.
I tried that the last time on LOD (gives really nice experience, since he takes long to kill for magic classes and constantly summons mobs) and it actually worked - kudos for Lexmark being the first bio I saw that *does* not start bombing instantly when another party tanks.
I miscalculated my damage though when I told him to go for it, so he MVPed anyway, but it was still cool. He even tanked it when I accidentally moved and LOD went on him, which made me feel bad X.x;
But yeah, loots were his, no question.
We went to Drake some time today too, and another party (Wiz/Dancer) was there first. So I lured Drake for them and tanked when the IW went down, and they left the loots for us without even saying anything (though we didn't take them; I believe they eventually disappeared, but then again, it was junk).
MVPing can work out just fine if the people involved actually think.
