Titan Ex, why do we stack behind boss?

[Vivejun]

I've always wondered why we do this. Why don't we spread out and dodge a single WOTL? You can really just eat a single WOTL and live through it, so why would you want to make 1 mega one that will instakill you?

I know the platform is small post heart, but there is still room. I don't really mean everyone spread out I guess. But why do the mages stack with the melee? There is room for them behind us for another line. I just wonder where this strat came from is all or why it is the most commonly used strat.

edit -

Stacking is ideal, but there is nothing wrong with stacking in a conga-line behind titan. In fact, it might be the better alternative.

This assures not only that there are guranteed safe zones, but also that a mistake doesn't mean eating every single plume.

i guess this is what im saying... why isnt the row the accepted method vs 1 stack.
