Bard is highly underestimated. Few people realize how powerful he is. This is one of the more difficult champions. because what sets a good bard apart from a bad, is planning. Ability to predict the outcome. Every single Bards ability can be considered useless in the wrong hands. Passive is inconsistent and requires time to be felt. Heal is extremely low and on a long cd, portals allow enemies to travel just like your teammates ( WTF, that doesn't HELP!!!), Q also depends on success and is fairly useless if there are no walls or 2 champions in a line, plus it has short range, and the ult, boy the ult....Doesn't do anything, just postpones the battle by 2.5 seconds. Yep, it is very easy to mess up with Bard, I'd say Tahm is more suited for trolling your teammates, but Bard is second in line. And yet, at the same time, Bard is one of the best supports out there, if you think before you do. bards Portal is his signature ability, that allows even the most stationary team move over great distance. Remember those times when in pro matches the whole team flashes over the enemy wall to attack the nexus. If Only they had Bard. Bard's portal can be a double edged sword, but not if you use it correctly. While Bard's e seems friendly to enemy champions, it is in fact an illusion. Bard's portal sets up a perfect binding position. enemy champions almost never know what they're getting into when they go through the portal, and even if u think that the portal doesn't help u escape, that is wrong. You move a lot faster through the portal, especially late game, the longer the tunnel is, the bigger the gap will be between u and the enemy team.
Absolutely always start with W, unless you're invading. With W you can put 2 shrines down in the jungle, that will stay there until consumed. This is immense help for champions without extreme health regeneration abilities, like amumu, eve, kindred, few jungling champions have early sustainability in the jungle, but even warwick will appreciate the extra help. after that it's pretty basic. I focus on leveling q first, with additional level in w on level 5, so as to increase the healing whilst you're away. also note that I level up e before the final mark of W, this is bcause at that point your heal has really little influence over your teammates, and an additional speed in portal is more useful since more temafights are starting to happen. I would even support leaving the last mark of Shrine to lvl 18. Remember that your W needs time for it's full potential. If you placed 3 shrines one after another and let them blossom, they can return to full health virtually anybody and give them insane speed boost to get away, but such precision requires planning that rarely comes to fruition.
