Thanks for the answers. Just wanted to let you know that I did in fact try Shen Jungle with your suggestions. Here are my experiences...
The first game, I forgot to get shadow dash and was useless early game... -_- We were up against a jungle Warwick and I could really feel the difference. I ganked as often as he did, but he killed every time where I would just make the opposing champion unnerved and go back to base lol. Warwick went legendary at one point - we still won thanks to an awesome Caitlyn and Eve. They ignored Ashe for a good long bit and she managed to get a good number of towers. Late game I finally caught up in items and ww can't carry the team especially when I taunt him out of his ulti. I ended up with 3-4-20ish
In the second game, the opposing jungle was Renekton. This time, I was more on top of getting ganks off and helping lanes and Renekton had a bad game getting killed very often. I could really feel the difference as there was also a Shen on the opposing team staying in lane. The blue and red buffs really made a difference in ganking. Then again, I didn't feel much resistance from the opposing team, so...I dk if I was jungling well or if they just weren't countering at all. Game ended pretty quick - went 6-2-17ish. For comparison's sake opposing Shen was 3-5-1 (remembered him insulting his team and I brought up that that he has only one assist O_o).
Overall, I do feel as it was slower to get experience and gold. In the beginning, levels are even. However, when rest of the team was level 9 or 10 for example, I was level 8. I usually go back after all 5 pots are used at around level 3-4. Pick up another cloth armor and some more potions. I really don't feel comfortable about ganking until I'm at least level 5. Also, I feel that teammates are better when I jungle...I'm not sure why. Maybe they can actually cs now that I'm doing something else lol...or maybe I just got really good MUs.
So followup questions:
1. I definitely did not ward as much as when I lane. When/where should I ward? At level 1 I feel like I really need those 5 pots and armor. Should I pick up a few wards when I go back? Also, where should I ward? Their Golem? Their Lizard? Dragon? I feel that dragon is probably best because it'll ward for bot ganks as well.
2. When should I gank? When I see low hp? Or even when they are full once in a while just keep them on their toes?
3. If I see opposing jungle (and likewise he should probably see me), should I call for gank? I'm pretty sure I can't win 1v1 against any other jungle out there.
Thanks, SomniumProxy for the guide and the help. Any anyone else feel free to respond and correct/help me as well. Don't want to seem like I'm trying to have a 1:1 conversation in a forum. I'm kinda liking the jungle . Though I probably need to pick up a jungle specific champ.
