Pink Ward - One per player

Before Patch 6.1 ( i think) each player was allowed 2 pink wards. After Patch 6.x it's now 1 per player and CD for has increased, duration of Trinket is decreased.

Vision is a constraint now. There can only be 5 pink , with 2 gone for drag+baron, that leaves with just 3. Which again will be used as defensive vision ( not even gank defense). i.e. have to be dependent on vision trinket. A trinket will last 60-120 seconds and once it is exhausted gotta wait 1 min before I can use a new one... sitting duck. If I want to go offensive, i'll replace trinket with sweeping ward and wait for 2 mins before I can use it.

Should ROIT reduce their CD ? 2 mins is a lot of time, It's enough to get an ACE, 2 tower or may be Nexus too. Or allow 2 per player?

Some suggest to use , but it doesn't provide true vision or hold more than one charge even thou enemy can see it. - It's a defensive vision if one likes to visit shop regularly past lvl 9.
