the total cost of ships with gravitic hooks seems to be not worth it as of the current meta
right now having mostly line ships with a few escorts are favored
Emissary sacea + 2x warden = 186 points + 2 extra ion cannons
Emissary borkan = 192
the only real advantage of the latter is bringing extra escorts without increasing the cap, but it does that job cost inefficiently so its usefulness as of today`s meta isnt really that high.

proposal, price reductions for the regular custodian to 460-470 points and the emissary borkan to 160-170 points

also if possible a cheaper non gravitic hook version of the custodian possibly with more ion cannons would be nice... (400-420 point range)

also note that the custodian itself is not as powerful as 2x protectors despite its cost and despite being a battleship, which ingame bring more armor HP and firepower than cruisers per point.

custodian = 500
protector 2x + 3 wardens = 506 + 400 more hp + 200 more shields + + 2 torpedoes - 2 hangar bays + high energy turn... firepower is equivalent
price of 2 protectors = 392

gravitic hook custodian should prolly be priced in the 400-420 range with the non gravitic hook version. non gravitic hook version at 320-340

Gravitic hooks are kinda awkward. I don't really understand the point of them existing in their current state. If they gave discounted escorts it would make some sense.

Custodian isn't that bad since it lets you have a strong flagship, otherwise Tau is very vulnerable to getting their moral stomped.

the deimurg stronghold is a better option than the super expensive custodian as both a tank and a defensive weapon to be honest... the only real advantage of the custodian is its 6x hangar bays
