Almost always go cloth 5 eh? I collected data from every game played at IEM Kiev last month and here's what I got:you're joking right
have you been watching tournament games at all
i mean sure you can start boots 3 pot or vamp scepter on shyvana or lee sin and still easily do a full jungle clear
but top junglers NEVER DO. they almost ALWAYS go cloth armor 5 pot. getting a wriggle's as fast as possible may be financially sound but it's rarely the best way to go in an actual game, where there's the threat of running into enemy champions in jungle as well as variability in ganking and in jungle paths.
regrowth/boots openings definitely are possible on some of the most popular junglers out there but that does not by any mean disqualify cloth five pots as a waste of money. far from it. what with mundo's lack of sustain, it would be unsafe to start anything BESIDES cloth 5 pot unless you're planning on just jungling until four, backing, and farming more as opposed to an invade-heavy, duel-heavy path that mundo really excels at.
cloth 5 pot - Occured 11 times: lee sin/shyvana in m5 vs sypher, lee sin in sk vs curse, shyvana in m5 vs dignitas, gangplank in sk vs dignitas g2, gangplank in dignitas vs solomid g2, shyvana in m5 vs sk g1, shyvana in m5 vs sk g2, lee sin in solomid vs m5 g1, lee sin/shyvana in solomid vs m5 g2, lee sin in solomid vs m5 g3
Notably, occured only on 3 characters: lee sin, shyvana, and gangplank. Certainly 3 of the better junglers in the game at the moment, but hardly the only viable 3 or even the top 3. Interestingly, neither shyvana nor gangplank presents a large threat for a gank at low levels, which may be why they chose the more sustained/safe build.
boots 3 pot- Occured 7 times: lee sin in white lotus vs curse, shaco/rammus in sypher vs AAA, shaco in AAA vs dignitas, udyr in sypher vs dignitas, pantheon in sk vs dignitas g1, lee sin in dignitas vs solomid g1
Had the most varied champion representation, occuring on 5 different characters. Most common on champions that have strong ganks at early levels such as shaco, lee sin, and udyr.
regrowth 1 pot - Occured 18 times: maokai in white lotus vs curse, maokai/skarner in sk vs white lotus, maokai in AAA vs dignitas, maokai in sypher vs dignitas, rammus/skarner in solomid vs curse, rammus/skarner in solomid vs sk, rammus in sk vs curse, maokai in sk vs dignitas g1, maokai in sk vs dignitas g2, maokai/skarner in sk vs dignitas g3, skarner in dignitas vs solomid g1, maokai in dignitas vs solomid g2, rammus in sk vs m5 g1, skarner in solomid vs m5 g1, skarner in solomid vs m5 g3
Only occured on 3 different champions, but was the only build used on both maokai and skarner, two of the strongest junglers in the game at the moment. By far the most popular build on Rammus as well, with only one game being different.
dorans blade - Occured 1 time: lee sin in m5 vs dignitas
A build that I have seen some lee sin players use, but not very often. Trades safety in the jungle for speed and powerful early ganks.
cloth pots/ward - Ocurred 1 time: udyr in sk vs m5 g2
This is a slight variation on the cloth/ 5 pot build that was only used one time in the tournament, and I have only seen a few other times.
So yeah, you might want to watch some tournament games yourself before you go making outrageous claims like "top junglers never start with anything but cloth/5".
