Edit: Okay, I made it all the way though the thread, versus reading just the original post of QQ.
While the rhetoric was cute it didn't help your case at all. Details are needed. What was the armor/shield combination for the Maddy-1. Note that -1 is standard /1 is ADV and v.0 is PRO. If the armor was 2700 when maxed the repair units and/or hardener combination was your stumbling block. Depending on what was included for small turrets and whether the tanker was using an IOC or NB (something else you neglected to share) the amount of CPU/PG can vary dramatically.
Scanners: Yes or No?
Damage mods, even heat sinks show as a damage modifier (I think so anyway).
Without more information it is difficult to solve your situation. No hardeners might mean triple repairs at complex level with a PROTO tank DRIVER. Possibly four repairs, Base or Complex. Enhanced armor repair units are an insult. Nobody should waste any ISK on them.
The other thing to remember is he (generic he, you gave us no name) had your number. You lost how many fits and he mowed you down. Which means you came here an rage posted. Which means, he really, really had your number. Each death means he has 10 seconds to recover his armor. He only needs 9. If the team cannot coordinate your volleys, you might as well be playing solo. And considering how he shot you down, controlled the battle you should have thought like a tanker. Go do something else when you are outmatched.
A tanker that thinks like you did, well he loses tanks.
My original knee jerk reaction:
Sorry, from my experience they aren't.
However, compared to the paper tanks laughingly called shield tanks they are considerably easier to fit for survivability. Shield vehicles suck. That is the reason most run armor.
Armor tanks can double hardeners and repair modules. The higher the level of tank, the higher BOTH can go. Proto allows dual Complex Hardeners and dual Complex Heavy Armor Repair. A driver that is aware of their surroundings, how many are chasing after them (with murder in their hearts), and is familiar with the layout of the map in the specific battle mode and with the particular sockets the map came with - they can survive quite a bit.
However, if you get stuck on a box, a ladder, a ramp, a cliff edge or one of a hundred problem areas that a real tank would drive right over and your very expensive tank is just another smoking ruin.
Now, if you come after in my armor tank Maddy ADV/PRO and you are alone with MLT to STD gear, well have a good time making +75WP for damaging me but
unless I make a mistake you will not kill me. Your buddy running up behind me with those stinking Lai Dai Packed AV grenades - he will.
Which is why I try not to sit still for all that long.
