something doesnt add up, i have played enough to know a IS2, pershing almost fully wipes squads in a single shot while both KT and tiger usually just snipes models. I have better luck with hits from Tiger 1 than the KT.
...you do realise that all heavy tank AOE was recently (as in two weeks ago) completely changed? Their one shot kill radius was reduced but their health damage radius was increased, along with an increase in the chance to hit squads, so that they will deal more consistent damage to infantry instead of being RNG wipe-or-miss fests.
The Tiger II got pretty much the best AOE out of those changes, as shown above, although it's only slightly ahead of the IS-2 and Pershing.
Also comparing a cheap TD such as jacksons fire rate to the investment of KT is not fair. KT will mostly fight of infantry which is sucks at doing because of its shitty firerate.
Why do you insist the rate of fire is shitty? The reload is really good for the damage it does compared to most/all other vehicles. 6.25s is a really good reload. A Panzer IV has (160dmg) has 5.75s. The Pershing (160dmg) has 6.75s. The IS-2 (160dmg) has 6.65s. The Tiger has (160dmg) has 5.25s.
There is absolutely no reason to think the Tiger II's reload is "shitty". It's above most other heavy tanks, only second to the Tiger I by 1s, but it deals 50% more damage per shot. The only downside to its reload is that it doesn't get a veterancy reload bonus until vet 5 while most other tanks get it at vet 3.
Again, its AOE and scatter got a major buff in the recent patch, and now it generally forces squads to retreat in ~2 shots. It no longer sucks at fighting infantry.
You cant just spearhead into the enemy with the KT because it will die due to not being able to absorb damage.
Not able to absorb damage? It has 375 armor (highest in the game for heavy tanks shared with IS-2, but the IS-2 has less health) AND 1280hp (highest in the game for heavy tanks shared with Tiger Ace, but the Tiger Ace has less armor). It is literally the most durable tank in the game right now.
Your opinion on the Tiger II seems to be pretty much entirely based on misinformation and misconception.
