Wouldn't say that's true.. I've been leveling an alt of the same class I'm 13/13M on, and I actually die a lot, some abilities are really badly scaled, like some dots ticking at 1k hp when you have 2k HP.
I didn't mind until it happened in Tarren Mills and it's like a 5 mins body walk.
But good for you if you didn't die much, but I can assure you between level 30 and 60 I've seen lots of useless deaths due to bad scalling, like if sometimes it didn't register my own level first but the one of another person, and that also happened on some trash mobs that started to hit a lot harder than expected.
