For real, did you seriously like season 5?
Ok, one thing to note. I didn't totally like season 5 (or this preseason). But I think riot has at least "tried" to make it on course on 5.22 to make things right. They are still attempting. What I'm saying here? Well season 5, although innovational was a very restrictive meta. In which you were** "forced"** to do certain things, and "mistakes" were made.
First hand came the jungle which in the preseason, if my memory is correct Warwick, Vi and J4 and fiddlesticks were only viable. If you can't play these champions, basically you were not allowed to jungle since the harshness of the camps kicked out many junglers out. (If you played in this environment, warwick had a 90% pick or ban. Hardly balanced than yasuo or tyrn this year) This had many complaints, which made certain champions** "non-existant"** rather than being** "off-meta"** most notably, poor nautilus.
Next came what can be said the most changing element of season 5. The cinderhulk. Although innovative, it produced a lot of abusive gameplay tactics, such as the top-laner smite gromp start which only the blue side toplaner had access to, denying every autoattack from your foe. And of course cinderhulk made 3 unkillable champions on either side, making one teamfight cost you three turrets. (Ok and you thought only in this patch one teamfight will cost you a total game.) The top tp LVL2 tactic also came around this point which I believe is still one of the largest culprits of your enemy snowballing if your champion was unable to do it. This lvl2 teleport was the start of the concept of **"skipping laning phase" **in which in tournament scenes became rampant, to the point in worlds they entirely skipped it making a lot of viewers disspointed of the lack of action because of "stalling" of the already long 40-min game time. If you remember in season 5 there was a period around 30-40 mins in which no other side was able to get objectives, **but revolve around the map in circles for 10 mins in hope of catching the unlucky someone. ** Since humans are not perfect and waiting for that mistake to come out for 10 mins is not about tactics or skills was unfair, good player, bad players and even pros did suffered from this needless time zone. Wards do expire, people might group or not because of the time, it was rather about which side has more damn luck.
What do you think? Was season 5 perfect? No it hardly isn't. And for me, it was quite tiresome in some points, and I believe in riot that they are showing some sort of action to remove these element that were a contraversial issue. And I doubt this preseason it would stay like it is now.
