Has the game really changed that much that this is now classed as "pants" set-up??
Yeah, pretty much. That set is pretty low end, and executioners axe has crappy specials. My advice would be either hunt liches, or whatever the strongest thing you can handle for better armor, or simply hire an imbuer to make you a suit of Studded Leather or Bone, with:
70 in all resists (or as close as they can get without using special ingredients) 7% LMC +4 HP, +7 Mana, and +7 Stamina on every piece. Jewelry: +13 DCI, +13 HCI, +22 Damage increase, +7 Str, +7 Int. Swap int for dex if you int is above 30ish.
This suit won't require anything but gems and imbuing base material, so it won't be super expensive, and it's basic, but VERY functional.
As for your template, really it's just fine, with the exception of focus. You can get enough stamina from divine fury or potions if you are fighting anything lower than a boss (and some bosses), or stamina leech. Assuming you want to maintain a "classic" warrior feel, I would suggest swapping out Focus for 120 Parry, and from the Executioners Axe to a Broadsword and shield. You can find some really great shields out there to help you get your DCI up to near max, as well as help with swing speed increase. If you don't mind expanding character concept, consider mixing in Necro for vampirc embrace and Bushido. There are many build ideas on the Warrior forums.
If you are more set on two handed, and axes specifically, I would say add resist, and switch to a Double Axe, which has two good specials, and is a nice all around weapon.
Have someone make you a basic weapon to use with:
Damage increase: 45
Hit mana leech: 55
Hit life leech: 55
Swing speed increase 25%
Hit lower defense: 44%
This also requires no special ingredients so, should be cheap as well.
Get a swamp dragon, and some dragon plating. They are ugly as hell, but the 20% damage reduction is a MASSIVE boost, and will keep you in the game where otherwise you would be toast.
From there, do you have clean up points? If so get one of the talismans that gives you +5% HIC and +10% damage. From there go find the strongest thing you can kill without issue, lich lords, dragons, and stuff like that should't be much trouble with this set up. Hunt up the best shield you can find, with +20% DCI, and +10 SSI as a base. In combat EEO everything, keep Divine Fury up for the +!5% hci, so long as the dci hit isn't getting you killed. Use armor ignore and double strike as often as possible, keep consecrate weapon up, and bandages flying.
From there get yourself a set of slayer weapons, with the same set up replacing HLD with the slayer. Those will be a bit more costly, but most of them you can hunt down the stuff yourself to give to your imbuer to offset costs. At least one of each super slayer, and a few specific slayers like Scorpian (for Miasma) and maybe dragon or something if you want to try ancient wyrms or greater dragons.
Really from here you are baseline good to go in any group situation. You won't be the powerhouse but you can do good damage, and heal if need be, and tank if getting healed in many situations.
From there look into what artifacts you might be interested in, mainly gonna look at the stuff you can get from blackthorns. See if you can find a parter to cross heal, or others to just group with to take on blackthorn captains to earn yourself some. Read up on the warriors forum for template and suit ideas, and slowly get those stats up to max with additions, and within a reasonable amount of time you'll be ready to tackle most bosses solo.
Hope this was helpful and isn't too overwhelming!
