Please stop thinking 3 strategists is meta and it means an automatic win (It’s not). And people seriously underestimate the importance of tanks
I lost a perfectly winnable rank up game at 96/100 points in Platinum 1 because the team mid way decided 3 supports was a guaranteed win and it was a tank that switched off so we were left with one tank
The role of a tank, is to tank (yea shocking). They push up against the enemy team because they have a large health pool so making space for the rest of your team with less hp will be safer, so 70% of the time all the enemy’s damage output will be concentrated on the tanks. The problem with 1 tank is that all the enemy’s damage will be unleashed on 1 tank, even with 3 strategists it may not be enough to complete heal them through the damage of 4-5 players, there’s also the factor that strategists may also have to heal the dps’ which draw attention away from the singular tank and 2 healers pocketing may not be enough
2 tanks on the other hand will spread out the damage throughout 2 teammates making it easier to heal because the damage spreading out means the tank’s health will deplete less quickly thus less likely to explode when walking up to make space.
Moral of the story 3 supports isn’t an automatic win and isn’t meta, 2 tanks is by far the most important aspect to have on the team of equal importance to having 2 supports minimum.
Although i have won games with 1 tank but it’s either because the enemy team’s damage output was really low or the solo tank is doing some streamer doing Bronze to GM climb solo queue. Both scenarios are very rare so don’t bet on a solo tank
