The best of being a Tank is being the Tank it’s that simple.
I come from the original game I4 to shutdown. My 1 and only 50 was an INV/SS tank which I am rebuilding here from memory. I could take on just about anything at lvl 50 without worry of dying. I racked up the debt badges getting there because I played solo at times, not always a good thing for a tank at certain levels, but it was still fun.
I stood toe to toe with AV while the team I was on cleaned up a second group that was close by. I could beat it but I stood there and battle it until the cavalry arrived and we took the AV out.
Other memory was during Halloween event when Jack of Irons could be found in one of the zones, the name escapes now, but I came across him beating on a full team of lower level toons who were not doing well. I gave them a hand by jumping in and keeping his attention while they took him down.
I was taught by a great Tanker for the time and I try to pay it forward if I can.
