>_< Jile, I'm sorry if my attempt to support your post caused it to derail a bit... I really was only trying to support the repairing of Reward only.
The example of Tenzen II fight does work as an illustration for the majority of the intentionally introduced problems with BST, but let's all try to focus on only Reward for now.
As it stands right now, there is no indicator that our pets have changed targets and have decided on their own to teleport out of Reward range. This can result in the pet dying due to a system error even if Reward is off cooldown solely due to the range limitation. Even if the teleporting-when-agro'd glitch were corrected, which I really don't see happening at this point due to the depth of that problem (would likely require a full replacement for all of the pet AIs), then at the very least, Reward still needs an increase in range equal to the range that the pet can randomly poof off to. Somewhere around the 20y range should probably be enough to compensate as a workaround to gloss over the glitch at least.

While on the topic of Reward, can someone please tell the dev's to stop giving us gear with potency please? Reward+30 does exactly zilch due to reforged AF/relic easily overcapping with a mere two pieces, which also provide additional essential augments so currently it is a 100% factual "bad choice" to use anything else. Stuff like the BST cape from Ambuscade or the feet from Sinister Reign make me sad that everyone else gets usuable stats on theirs, but mine basically has a blank line on it. It might as well read "Reward +0" as that is what the impact of equipping it is.
More recast reduction would be nice instead, but basically anything would be better than that "blank line".
