Obligatory get gud comment. Now that I've done that here are some tips for taking down the exploration blights solo. You will need a high impact sniper and good rocket launcher. Red Death will also help because of the health regen but is not required. Pay attention to the updates above your super bar what you're looking for is "A Taken Luitenant is corrupting the land". These luitenants rarely spawn within your line of sight so check around. After you kill 3 of them the ultra will spawn use all of your rockets and supers at whatever range you like (hunter GG with 6x helm is awesome) then sit back and use your sniper rifle to mitigate incoming damage. DO NOT SIT STILL, take a shot move a little take another most ultra attacks will arc allowing you to dodge. Recommend light: 275 (solo) 250 (duo)
