Major bug, or has it always been this way and I never noticed?

Last night after targeting myself (with F1) so I could use my Shrink Shoulders...I forgot that I was still targeting myself.

I engaged a mob and cast Slow, and Dot'ed them. Took me a moment, but then I noticed that I was slowed and dot'ed myself!

It was then I realized that if you target yourself, you can cast almost any of your own detrimental spells on yourself. These include; roots, snares, slows, nukes, dots, blinds, stat debuffs, and fears. Rain spells and AoE damage spells didn't land on myself when cast like this. I didn't have lulls or mezzes to try out either.

I THOUGHT that this was a major bug here in Legends, but someone mentioned to me it's always been like this in EQ.
I have played EQ since the beginning, and I don't remember this being a thing at all.

Anyone else?
