I know this is an old thread but thought to add what i have found either by experience (very limited im still classed as early game noob) and what i have read from various sources online. Norma 5* with top gear has got me past Basic 50, Vesa 5* with top gear has almost got me to Basic 100. I have used Heart Watcher 5*, Lutz 5*, Blood Blade 5* and Dominator 5* as i have heard they are also good beginner picks. Im still trying to brake Basic level but i am getting close. I believe i might need 6* heroes to get further unless someone is able to share their tips for beginners on this.
