Wards Time is Extreme Short

Wards time is from 1 to 2 minutes, (depends on your champ level) So actually this time duration is like if you went base to buy item and comes back to that ward place to put another ward, probably enemy team will be waiting for you to come, and hunt you.

1 And 2 minute is like 5% of players buying the control ward for that, control ward is way needed to remove wards more than to make a vision.
So actually we don't have the all time to go an unknown place that actually (dangerous) and put a ward, that going to help for 1 minute.?
Every game i have 2 ~ 3 players with perma wards 1~2 all the game, 
Not only they are lazy to put wards, i have ask many, reason because wards expired very fast,

for example ur ward on 40 second, you went to help mid laner, you back, and that place ur ward expired the enemy killed you there. The reason? the reason that he knows its just expired now, and you might come here now, with no visions. 1~2 minute is extreme short time, while everyone needs to farm, and to help, and to back base as well.

support also, having a 5 wards, with 3 limited wards, however im as a support i have my 2~5 wards mostly like 20% of game time,
just sticking around with no idea my wards are expired in flash of closed eyes.

maybe this can be fix by giving 1 instead of 2 wards, and ward time is increased to 5 minutes, this way also support will be having fun.
