What can we expect in the pre season for season 6?

We are almost there, to the finish line and i'm wondering what kind of changes we will go through. My guess is that this time the changes will be a bit less massive in scale compared to the last 2 season. I say that because this is the season with the most significant changes DURING the season, meaning less drastic things to do in the pre season

But that doesn't mean that we wont see much, infasct i expect anyway tons of changes, let's see what i think we could have this pre season:

• Rune system overhaul: Complete overhaul of the rune system, it has been rumored somehow before and i think this is much needed, cause that system it's not really interesting as of now and has tons of problems. • ADC Itemization: I think we will see more option for marksmen this year, in a significant way. This is also really needed since we have 2-3- buildpathbetween all adc pretty much. • Mastery updaes: I think this system will need a complete revamp as well, but for now i think we will get some changes to it, but nothing super impactful. • New client update: with that i hope it's a massive update, couse well we need it badly. The client of League is very old and need some drastic changes. • New general items for all roles: More items will be added, i'm pretty sure, something may be removed (Poacher knife) • More Mastery level (6-7) to earn with each champion • Meaningful ways to use your IP (I have 100000 IP and i don't know how to use them) • Support items, exp check: with that i mean an upgradable Sighstone , and an fixing the problem of the low experience gained by supports (and possibly junglers sometimes)

Then we may get something that we cannot imagine like i don't know, new jungle camps, crazy things like new stats, new game modes and so on.
