11 speed question

[Penny4]

So, i currently have on my road bike:
Shimano R600, 50/34 (compact) , Shimano 105 11-28, 10 speed.

So will the new 11 speeds give me a lower (aka easier for hills) gear? Or is it just going to give me more fine tuning than what i currently have?

I don't think i can put an 11 speed cassette on my current bike. But, just asking in general if the 11speed will give me that extra easy gear I'm always praying for mid climb :-)
