Should I just play shyvana as kind of an "attack nunu".

Shyvana is the farming jg. she's super efficient in terms of farming. She has come back into the meta a bit because of recent buffs and isn't picked alot because she just farms due to the lack of ganks. Anyways, shyvana is known to be a good counter jungler. The few that can beat her are xin zhao, Yi, trundle, and Warwick at least until the late game. The reason I say "attack nunu is because nunu is the counterjungler. Ive also played and his ganks are sub par and he can't really fight that well. His use has been defined as not making the enemy jg useless but discoing it down mid XD. Don't do that. Just as bad as inting and riot, fix your ban system. Anyways he just keeps stealing camps. Instead taking camps, you also hunt the enemy jg and gut them like a fish. What this does is puts them behind in gold and exp because they lose camps and play black and white simulator while you take camps.if they try taking your shit, they've just kicked a hornets nest because you have your teammates. They can help you. Also the way I do it is I start whatever side they are least likely to start like if it's an Eve or elise, I start their red but if they normally start red, u start their blue. If they can do either or, I start top side. I don just take the buff, I also take the raptors for red and for blue, I get both gromp and wolves. That slows their lvl 3 down by like a whole minute enough time to clear the rest of my jg and back for items. I also take scuttle for HP. So I can clear an extra camp. Of course, you need to gank if you can. I tried this strategy against a ww and I put him at a lasting gold and lvl disadvantage. I couldn't beat him 1v1 though but they eventually surrendered at 20 because our ADC was good. Anyways, is this a good way to use shyvana.
