recon and stealth I can respect, being a sniper man myself, but the rest seem to be super specific use cases. Even for recon and tealth though there are alternatives to teleportation, and again, with only two slots, we need to conserve these slots.
I can understand where you are coming from. But when I think of abilities and weapons I think of them in their totality as much as I think of them in specific uses. Ad libbing something Batman said in a movie once, "If we believe there's even a percent chance that it can happen, we have to take it as an absolute certainty." So I also think about things like outliers and murphy's law when I view things like this. Although to try and keep my posts short I try to focus on the uses I think most other people would use if they was thinking tactically. We could also pull in ideas from other games to see how they use teleporting part of game play besides movement.
For example, I use to play an MMO called Wakfu and one of the characters I mained as was an Eliotrope, a race of beings who are known for being able to open portals at will. In combat not only could you use the portals for movement to teleport yourself and teammates around the battlefield, but you could also use them to attack as well. Two of the most common ways people used portals to attack was to extend the range of your own attacks or your teammate's attack (example an arrow can only go so far but it can go farther with the extra help of the portal) and/or by redirecting the attack (opening a portal behind an enemy who is behind cover to let you fire an energy beam through the portal to hit them in the back. The portals themselves are an utility ability so by themselves they don't really do anything on their own, outside of giving people portal sickness (a kind of motion sickness) if they jump into them to many times in a row.
Or look at how Loki players use Switch Teleport in Warframe to troll enemies and sometimes teammates.
Because of how I like to play games I also love to use utility abilities in odd ways to do things. And there are a lot of ways I can use short range teleporting to do things both in and out of combat. No different from how I might use a healing spell on an enemy in some games to kill them. Because in some games using healing magic on undead enemies hurt them and using revive magic is a one hit kill on undead. But also some abilities only work their best if the enemy HP is within a given rage. Like how some abilities only do extra damage and effects if the enemy is at full health. While others abilities might only work best if the enemy is at like 45% health. So healing the enemy seems at first counterintuitive until to factor in the abilities of other characters/classes/players.
