PSA: Max W on Tahm Kench as support

There is really no real reason to max his Q in lane unless you are against poke and need hard disengage.

His Q will stun for 1.5 seconds at ALL ranks once they have 3 stacks, maxing his W is beneficial not only for making the odds more in your favor, but if your ADC is dying, you can eat him/her and run away, using E if you are about to die.

Maxing W is arguably one of the best things as Tahm as a support as it will save your teammate, have a lower CD, and make some enemies gone from the fight for a few seconds.

Maxing Q only increases the base damage, and slow%, not the CD or the stun duration.
