I usually dont discuss in forums but as coh2 fan i must reply to this post. I also see more threads about tiger but i ll respond to this one for now.
Welcome to .org then!
I think people who complain want to say that tiger is just slightly underperforming for its cost and mostly cheaper units can counter it easily. I dont think it should be super tank,far from that,it should be countered,but if it is a heavy tank it should act like one. I consider it very fragile atm(and thats funny considering its size) and needs a babysitting a lot atm because of his bad frontal armour,whatever people,say it really is penetrated by everything.
And for the reason of being slightly underperforming, it got recently considerable penetration buff and +5 range buff, which puts it far above all generalist tanks in game.
I think it frontal armour part(nerfing rear armour is good actually as it rewards flanking) should be increased as tiger is really slow and its hard to escape if it is damaged in battle.( combine arms battle i mean,i never go alone with it). And even when you do escape,it needs forever to repair it what is really annoying. It should be a little harder to take it down imo.
Thing with tiger is, it have 3rd best suitability(no generalist tank except IS-2 can take it on frontally, even equally expensive Pershing) with only KT and IS-2 having more, but it got also excellent firepower that only KT and vetted Pershing can rival with.
It feels weak, because allies, contrary to majority of axis players, actually do use tank destroyers, which are natural counter to Tiger. No medium stands up to it, all of them need to flank or use additional units or abilities to inflict considerable damage.
Repair issue is a whole another story and is a problem of both vanila armies, pios and CEs alone just don't cut it in comparison to all later armies repair speeds and options.
There isn't a problem with Tiger survivability, there is a problem with players mindset in this thread, who believe a tank should resist its hardcounter, tank destroyer.
There is no allied tank except for IS-2 that can go toe to toe with Tiger for the cost, TDs are sole counters and they will only be better against heavies(while less effective vs meds).
Thing is, in the past, players build armies AROUND the tiger.
Its not possible, because its not on godly level anymore, now you build your army with Tiger as addition, not the backbone.
