I am all for speculation. Speculation is what made Avatar fun tbh. It was great just thinking "OOOO what's this gonna be like", "oooo what's THAT gonna be like" and looking back on my old posts, it seems like we all had good funr inspite of the turtle fail and every other fail . That said, people PLEASE FOR THE LOVE OF GOD TO SAVE YOUR SELVES, STOP SHIPPING. The series isn't even here yet and while it's great that they've decided to whet our tongues with some juicy tidbits, all this speculation on who is gonna be like who is desperately wrong.
For one thing, stop comparing Makorra to Kataang or Zutara. They may be fictional characters but LET THEM BE THEIR OWN CHARACTERS FTLOG. NO. Mako is not Zuko, nor is he Katara nor is he Aang! Just because he fits into the same character set as one of those characters does not make him exactly the same NOR does that make the dynamics of the relationship the same. All the same, Korra is not Katara, nor is she Zuko nor is she Aang. SHE IS HER OWN PERSON. So while Mako may have traits that make him like Zuko (firebender) and some traits that make him like Katara (rational person...well probably more rational) and Korra maybe like Aang (the Avatar) or even like Katara (waterbender) this does not mean that the relationship is gonna be the same. That's like saying that two couples with similar TRAITS (NOT EVEN PERSONALITIES) are gonna have the exact same relationship.
Would everyone PLEASE just stop trying to make baseless assumptions on relationships we've yet to even see? Yes srs bsns totally affected by the fanbase yet again, but gdi Tumblr, don't make me hurt you. It was probably a mistake to follow the Avatar tag.
eta: once again it is fine to speculate and get excited (I choose not to for personal reasons) but come on, Bryke aren't literary giants but cut them a little slack that they'll diversify their characters a bit?
