Missions & Complexes

The +5s are indeed a must for a top end Tengu.

Personally though and from alot of experience you wont need crystals unless your soloing 8/10s and the 10/10s. Id go into more detail but I have no idea which region your flying in.

A partial low grade crystal set actually is pretty good, alpha through to epsilon gives a huge boost.

The best part of the Tengus tank is the ability to sig tank, Small signature and a 10mn afterburner negates ALOT of incoming DPS. In the 8/10 ded you will be webbed by the bastion so this is where you need more tank and should fit accordingly the same applies to the 10/10 bastions and the big torps which will take 30% of a tanked tengus shields on every volley.

I wouldn't use Snakes on a Tengu, waste of isk..

Partial low grade set of crystals = win.

If your gonna be doing cosmics like hubs,havens,sanctums etc then no crystals are required. You can get a very nice stable tank setup with 2 deadspace small shield boosters and a decent shield boost amp the rest being faction specific hardeners.

aye, crystals arent even required for soloing 8/10s and 10/10s better to put the isk into a better tank than the implants if your having troubles.

If I can ask whats wrong with an ancillary booster? I've had great success with the xl version in the past on my battleship fits and it means i can use the rig slots to augment dps rather than capacitor. I know I cant run it permanently like a normal booster but in the other situations ive not had to. The worst mission ive had to do was enemies abound part 5 where i had to run it through two full cycles to keep up with the dps. Having said that I'm still very new to Eve and im building my skills so like i said the fit is very fluid and im open to what should be changed.

tbh set of +5%'s rof, explosive rad and velocity and hml (if hml you useing) dmg is all you need crystal and snake are not needed and tbh ide go against em specificly for tengu and mission running as its another 1 - 2 bill on top of the tengu build.

As other have stated the ASB is for pvp situation not PVE.

Your using the amp node subsystem which bonuses for shield boost rep....yet your not getting that bonus at all whilst using the ASB.

If you want to use the ASB you should buy the adaptive shielding subsystem and gain 5% shield resistance per level.

You really should use the kinda of fit I placed. 2 deadspace small boosters with 1 shield boost amp work really very very well indeed and be is also cap stable.

You could also use a Large shield booster setup but that limits you to 5 launchers so the DPS is a bit lacking. Thats why I prefer the 2 small boosters. You get the very best of Gank and Tank.

ill place the fit i use in a few hours when im on eve for yah as it the best tank - gank you can get. dont be fooled though it is still killable in mission if you hit a trigger at the wrong time with better skills 1 wron trigger wont kill yah but 2 or 3 could

If your running Guristas, then a medium booster fit is decent. Lowsec/null you can use crystals to boost your reps further but t2 fit works perfectly.
