Because that defeats the entire purpose of this change - which is that the Water Strider is, and always has been, an overpowered mount for its requirements.
You should not have the choice of having water striding AND anti-daze/parachute because you did a reputation grind. No other reputation grind mount offers a special ability, the strider should be no different.
The fact is, like any other reputation mount, having the mount available to you is the reward for grinding the rep - not having free water walking. This is coming from someone that did the Anglers grind in Mists before they even add the commendations to make rev->exalted faster.
If you want be have water walking and anti-daze, then use your free water shoes mount equipment and buy some bridles from a leatherworker. You want to be able to survive if you get dismounted in air while still having water walking, buy some Goblin Gliders.
The Anglers reputation grind is not hard. The mount does not deserve special treatment.
Personally, I think they should add an additional item for herbing while mounted and remove the Sky Golemâs special too. Although that one at least has a valid argument since it is only crafted by a single profession and takes 30 days to make using items from multiple professions.
The only valid argument I have seen about the water strider thus far is that you only get 1 free water shoes item. If you did the rep grind for anglers, the item should be bind on account and free or 1 copper from the anglers so that you arenât actually losing anything.
