10 IV Attack Crunch Tyranitar...worth?
One of the Tyranitar I caught in a raid:
IT/C
IV: 14 10 15 (hp at df) 87%
Worth a Fast TM, lots of Candies and Dust ???
10 attack seems like particularly underwhelming, as it needs 5 more power-ups (lev 36.5) for BITE to perform as an att 15 one (lev 34) against Mewtwo lev 39 ACCORDING TO POKEBATTLER SIMULATIONS I ran.
It's my only Crunch Tyranitar out of 7 BY NOW
I have 2 other B/SE (att 15 & 14).

It/C is excellent for defense but I don't use Crunch for attacking. It has such a low dps, 22.3. Crunch is 3 bar move with a 3.2 second duration. That is 9.8 seconds that your are unable to dodge, or spam your fast attack. If you had been using a Tyrantar with Bite that would be almost 150 damage and 80 energy per 100 energy earned,a full energy bar. Which you usually can 2 or 3 per battle. Stone edge has 54.3 DPS with a 2.3 second duration. Crunch leaves you defenceless and passive much too long to be a viable attacking charge move. Crunches only positive is when used defensively you might get one off before a Machamp/Heracross slaughters it. I current meta though Tyranitaur shouldn't be used for defense since it can be so easily type countered like a Gyrados.
