Its a VERY small annoyance that plagues the game as of current, in a game filled with a ton more issues than just stack splitting. Again, they probably have all of three people working on this game currently, would you rather them spend god knows how long trying to fix stack splitting in the current game or trying to port the game over to a new engine where it would be a TON easier to fix issues that have plagued the game since launch. I'd almost rather them turn stack splitting back on just to see the crying that the server needs a restart every other hour. Unfortunately FE doesn't have the luxury of having a large dev team like most MMO's. So yes, adapting to the current way things are would probably be the best option, or they could spend weeks to months trying to figure out the stack splitting issue with no results, and have no progress in any which direction. Sure, it'd be nice if it were fixed, but in the grand scheme of things it is not a huge issue. And for those of you who say you love FE but then turn around and go "well I'm not going to sub until splitting is fixed" good job, you are only securing FE's death.
If you expect me to read this without proper capitalization and lack of paragraphs, oh boy you are wrong.
