Need some help with Mordekaiser
I've been playing
bot lane quite a lot with a friend of mine that usually plays
, and I must say that I find it really amusing to play. It's really unique, you gain extra benefit for securing the objectives (minions, dragon) and overall feels like a total monster to play as... as long as you bring your slave support along with you.
I am conflicted on whether to choose between
or
My build usually looks like this

I've been doing some testing with the two items, and it appears that sterak's is just above gunblade in terms of dps, but that's if you mix in trinity procs at the right moment. Sterak's also appears to be a lot cheaper, but doesn't offer the burst/slow that gunblade has, while sterak's has some nice survivability.
My question is simply; what item is more efficient to build? Should I prioritize the extra burst and slow, or go for more dps and survivability?
