...if you can see what stats are emphasized from the mission log.

I had a pet on a mission, and I forgot what stat it emphasized. Unfortunately, that isn't visible from the log, and the mission I was on, by everything in the description, seemed to be strength-based, and I pet I had on it wasn't. So I cancelled that mission, and then I find out that the mission is dexterity-based, and so was the pet. I was so angry because I wasted over 6 hours because the mission log won't show you mission focus, and the name and description of some missions are misleading.

Ugh. 12 more hours for something that should have been finished later this evening.

It can certainly be annoying but what you can do if you have a hard time remembering which mission emphasizes which stat is to make a list of them for your reference. You can refer to this whenever you need it and eventually you will likely come to memorize which mission is for which stat. However, keep the list and make a second list of which of your pets are for the various stats. It is always very possible to accidentally assign the wrong pet and having lists of which missions and which pets are for which stat is a big help with that. Mistakes always happen so your best option is to be as prepared as you can be ^_^

Hope this helps, sorry about your mission.
