What builds do people find interesting as a para?

Between Damage buff shouts and Area attacks Paras can deal decent damage. SoH, Find Their Weakness, Anthem of Envy (if I'm correct), I am the strongest, GDW/Splinter can do great damage. It's all about how you set up your heros/team. Paragons are meant for team play, they need the assistance of other players skills to boost their damage as well. (if this made any sense)

If I were a paragon I'd run something with leadership because without it, you might as well run another class. Paragons also don't tend to work well with casters when they don't go Imbagon: they have only a few skills triggering off spells (Song of Restoration; Aria of Zeal; Aria of Restoration).

The Burning Barrage and Focused Anger scythe (when enchant strips are rampant, Paragons are more armored than Dervishes: 80+10 vs 70+10 or so from Mysticism and up to another +20 from Windwalker) are probably the most solid builds on Khomet's wiki page for the above reason. Some of his stuff like Searing flames/RoJ on a Paragon make me go WTF (since Paragons have 2 pips of energy and without adrenaline-based shouts you get 0 energy from leadership).

I've use Soldier's Stance builds in the past too (PvP) before they hit the Wiki, which is the biggest example of Leadership use/abuse. Too boring for my tastes, but "Watch Yourself!" spam was good at the time (not so much now); Shields Up!" is decent in certain places (it had blocking before instead of +60 piercing); "Charge!" can be more useful than "Incoming!" at times; Protector's Defense suddenly becomes usable (yay). If you pump Motivation to 8 or 9, "The Power is Yours!" can be used as Finale of Restoration fodder if you decide to be "creative" and don't go Command.

I've experimented with Paragons in the past and the only skills I really like are TNTF, high-specced "Stand Your Ground!" (reminiscent of old "Watch Yourself!"), "Fall Back!", "Go For the Eyes!", the super-buffed "We Shall Return!" when sans-UA-monk, Anthem of Envy, "They're on Fire!" in NM when using Searing Flames eles (sorry, Burning refrain is way too conditional for me). On the damage front, Blazing Spear, Spear of Lightning, Vicious Attack (used with GFTE!), Spear of Fury are pretty solid and Wild Throw is useful. Stunning Strike is situationally useful (when used with Spear of Fury) against Ele bosses (that's about it). Merciless Spear is nice but there's too many sources of reliable deep wound these days.

There's a ton of skills I want to be buffed for Paragons that I submitted on GWWiki feedback but I guess Arenanet thinks Paragons are fine or something (motivation is sad). Some things like "Find Their Weakness!" , "Make Your Time!" would be pretty decent if they weren't so damn expensive and on mediocre recharge; other skills are ridiculously situational: "Brace Yourself!", "Can't Touch This!" (only in DoA's Stygian area), "Make Haste!" (Jade Quarry), "Never Give Up!" (theoretically could support a monk healing up an AoE spike), "Never Surrender!" (usable but the way it works could be tweaked to work like Recuperation), Angelic Protection/Angelic Bond (the only reason it can't be good is because it would be too good: see the version of Aegis in PvP or Divine Intervention), Anthem of Fury basically needs a 18-12 man team with at least 3 physicals that use adrenaline to warrant elite status, and Ballad of Restoration is vying for pre-prot status, Holy Spear has to vie with Spear of Redemption (underrated due to low adrenaline and anti-blind qualities) so only when there's tons of minions is it worth it. I'm still mad Soldier's Fury has an armor penalty that makes you equal to a caster (you are devoting your elite to it, it's not like the perma-IAS, Aggressive Refrain) and that Chants have aftercast (they're not spells, so wtf mate, Paragons need to build adrenaline by spear auto-attacking you know). With the change to Wearying Strike, I'd like to see a change to Wearying Spear too.

The only place I run Paragon in PVP is AB simply because of the 12-man nature of it. The more people there are, the better Leadership energy return is and the more effective party-wide shouts are.

"Save Yourselves!" is a warrior skill. Don't you forget that. The only reasons why P/W is better than P/W are the TNTF link to leadership and Focused Anger; Spear of Fury isn't linked to Leadership. TNTF is basically an anti-mesmer or anti-necro version of "Stand Your Ground!" since 30-35% damage reduction is roughly the same as +24 armor.

tl;dr: Sorry for the long post. Make sure your build uses/abuses/exploits Leadership.
