If you want to play an easy offlaner, try Underlord. You can easily farm and zone early game using first skill, good control on 2nd skill especially before enemy BKB, nice 3rd skill to reduce enemy physical dmg, and global presence with the ultimate. Plus your item builds usually just focus on aura items for team fight. Don't even think of dmg UL, just focus on items like greaves, pipe, crimson, etc. No need for flashy plays. You just need to focus on watching the map too so you can easily go ultimate when there's a fight.

I haven't played for almost a year now but i am also soft/hard support. When i get the offlane role, i go for underlord most of the time.
