Just started playing on Hardcore mode. Started with a level 43 Vanguard. I figured with my improved weapons and skills I'd blow through Eden Prime with ease.
My god was I wrong. The very first mobs I faced ripped through my shields like they weren't even there. I felt like Jenkins.
Before now I've never died on Eden Prime and I know things are only going to get worse.
Still, having to actually plan when and how to use my biotic/tech powers instead of whenever is going to be fun and challenging. To all those looking to play hardcore, remember cover and barrier are your friends!
