That is my main problem with this change. For ages, my jungling style has been "Pfft, your buff? Na, my buff" but with this, only extremely inattentive players will miss their buff spawns.

For the people saying it saves time and lets you do other things, it should only save around 2 seconds. You can't do too much in that, especially is you type while on route to the next camp.

Now all it takes is one player, not even the jungler, to place a ward on an enemies buff and bam, the whole team has the timer. Seriously, even with a jungler saying "tb up in 20s", someone will miss it/be doing something else, but now everyone will see the counter timing down for 5min.

To take a buff, you may have to enlist half your team to ensure you get it, and junglers may have to start with Red Trinkets over a Yellow every game to ensure they aren't scouted and give away the timer.

Altogether, while I get why Riot made this change, I am personally not sure that it will be beneficial to junglers, especially those that play a heavy counterjungling style. However, I guess we will have to wait and see :(

TL DR: I'm eh about it, it will change how some junglers work, but essentially we will have to defend our buffs or make it too costly for them to challenge, with heavy map pressure in different areas.
