However, there's a bit of a difference between being able to solo on a brute without planting, and being able to survive teamwipes on a blaster! Then you've become a tank-mage - perfect defences and perfect offense.
Yes, that's the point. In City, it is quite easy to become a tank-mage (or darn close to it) through many and various ways.
One of my favorite characters (out of many) was a Fire/Fire Blaster I made with 45.9% Def to S/L and 34% Def to Melee. Council in radio/paper mishes basically could not hit him, so I used him to gather up a ton of them (20-40) into a pull around a corner and just AoE'd them to death after Webnading them all down - Fireball up every 6 seconds, Fire Sword Circle every 6 sec, Burn every 7 sec, HotFeet, Crazy Stamina plus Consume (every minute or so), Rain of Fire every 25 sec, BuildUp and Aim every 30 seconds (I usually staggered them, so use Aim, wait 15 sec, use BU, repeat.), SuperSpeed+IO +Stealth for full invis, and of course for the stragglers, bosses, etc, my ST attacks of FireBlast(1.3 sec recharge) and Blaze (3.3 sec), as well as Fire Sword (3.6 sec rech), IOed KB prots, etc.
THIS was godmode, or tank-mage, or easy-mode, or whatever you want to call it. They inneffectually attacked me, to little or no damage - and I brought down armageddon on their heads. And these were not -1s, these were gobs of +1s and +2s. And a ton of XP. I was able to level him at a good clip, just as I like.
And this was far from my only character like this. I had two untouchable Stalkers, Def so high even incarnate content couldn't hit them without cheating. A Dom with PermaDom. A FF/Bot MasterMind. A Storm/Illusion troller (I think). And countless Corruptors. A couple of Brutes, including a Fire/Fire. And more.
All had tricks up their sleeve for controlling the fight, not getting hit (or getting back health fast), and dealing tons of damage.
For the last few years, playing CoX - if you were moderately clever and could afford stuff on the market as well as stuff off the CoH store especially, you could play with little risk of loss or death, and lots of fun, glory, sizzle, and kicking butt.
I hopefully look forward to more of that.
