Obviously the vg shines not in duels, but in the thick of it, where he can move around and pick his spots out of range for other melee weapons while knights et al take the brunt of the front line action.
Yes, the way the Vanguard is now he isn’t really a shocktrooper like the name of the class sais, but he’s much more powerfull as a support class, where he aids allies with his long weapon stabbing distracted enmies without hitting teammates or being in their way. For some really offensive fighting they’re not that suited, or atleast not if the opponent knows what he’s doing. Noobs aren’t a big problem for a reasonable skilled Vanguard.
As a relative noob, I would say a combination of that and trying to flank enemy positions. Vanguards are fast enough to move around the map, and then powerful enough to make a big, big difference once you get there. It’s not uncommon for me to spend several lives getting my ass kicked before evening out the score with a flurry of kills when I do get in the right place at the right time. Even a sole vanguard steaming into the blindside of a deadlocked fight can clean house, releasing multiple teammates to get back on the charge. Two or three can be absolute carnage, sending entire teams of enemies back to the spawn point.
Also, although I found the vg class to be the first I got to grips with, it was most definitely NOT through LMB spamming. If you plan to spam the attack button, pick either of the other two melee classes. MAAs can spam fast, while Knights can go toe to toe and trade blows. A vg can’t do either. My noob strategy recommendation would be: get running and charge up an attack. Press the X key a few times to help build up a head of steam. Then, if you find an enemy and he’s looking at you, go around and do another lap until you find one that isn’t. Then kill him.
(But don’t actually use the charge attack. It sucks. If there is once balance tweak I’d like to see, it would be Vanguard charge attacks breaking blocks like a kick / shield bash. Not so the charging vanguard can attack again, but to give nearby allies an attack opportunity, and at least make the charging vanguard not immediately vulnerable to a counter attack. Launching yourself full length like that shouldn’t just be pinged aside like any other strike.)
Basically, you want to completely avoid fair fights. The longer a duel lasts, the less likely you are to win it. I tend to think of vanguards as being like the cavalry of the game. You can make an awesome initial impact, but you don’t want to get dragged into a brawl. You’re best charging, striking hard and then disengaging. Find evenly matched skirmishes, tip them quickly and decisively in your teams favour, and then away!
Feedback on what I’m doing from more experienced players would be very much welcomed.
