Hi Lamejake,

It's hard to analyse what's going on without knowing your entire build - if you could let us know your skills (and levels) it would help. It would also help to see a few matches posted or give us your glad's name and tier to look him up.
It sounds like you're relatively low-mid level, so keep in mind that at that point glads pull ahead and fall back fairly often since they're nowhere near complete and a lot of the time it's an attribute battle.
Also, heavy hitters do punch through defenses, and medium armour doesn't absorb as much damage as heavy (although you do get better mobility which lets you be more aggressive).With tanking there's no need to have a bloodlust higher than 1 when tanking (as you're not really going to be hitting back).

With your strategy try focusing on a few lines to get them working well. The strategy you have is very defensive - you only attack if you have more endurance and more health (hint: you can't wear down your opponent's health if you don't attack). Look through your matches and see if you can pinpoint if there's a particular condition or strategy line that's causing your losses. I suggest you try a more moderate approach with your strategy - warriors tend to do well in the endgame if they can withstand the initial onslaught. Perhaps you may want to get more aggressive as your opponent tires out, or as you lose health -> keep in mind that, other than line 1, the higher strategy line items will over-ride the lower ones if the trigger is true.
