Guild Wars 2

wew my first post on the forums after 2 years in the game, here it goes

since you chose ele and engi, i’d say engi offers the best high risk options for what you are looking do to (cele engi/ele are very strong, but medium risk at best)
i suggest running someting like VeeWees roaming build, similar to this: http://gw2skills.net/editor/?fdAQJAqalUUpErlcxvLseRCbBNqxAqNIyOWlPfgAkUA-T1hHABFp8jn9HA4EA0megFV/JgHAAUKBJFAMLrA-w

key points of the build are extreme aoe condition pressure and medium sustain/mobility to handle outnumbered situations
it does have some hard counters (necro, high condition pressure, cc chains), thats why i would still classify it as high risk

problem with ele is, most high risk options (usually berserker based builds with fresh air) are countered by thief, which is bad for wvw roaming

also let me tell you a bit about typical wvw roaming:

• you will spend most of your time running around, flipping camps, sentries and mercenaries, avoiding the enemy zerg or getting zerged
• most enemies you kill will be either alone (mainly thiefs), running to their zerg, trying to run away in general, have builds optimized for zerging or are inexpereinced pvpers. all of them should be relatively easy to handle for your group, if you are as good as you think you are
• fights against experienced pvpers will always be hard no matter what and outnumbered fights you can actually win will be rare

this is just to show you that if you want to be an actually useful wvw roamer that helps your server, you dont have to worry about fighting as much. there are enough things you can do with your group no matter what classes you pick.

if you’re especially looking for outnumbered fights tho try defending supply camps (anywhere) or towers (low populated areas)

this is all just my experience ofc, others might disagree
